BACKGROUND OF THE INVENTION

The protein kinases represent a large family of proteins that play a central role in the regulation of a wide variety of cellular processes and maintenance of cellular function. A partial, non-limiting, list of these kinases include: non-receptor tyrosine kinases such as the Tec family (BTK, ITK, Tec, ETK/BMX & RLK/TXK), Janus kinase family (Jak1, Jak2, Jak3 and Tyk2); the fusion kinases, such as BCR-Abl, focal adhesion kinase (FAK), Fes, Lek and Syk; receptor tyrosine kinases such as epidermal growth factor receptor (EGFR), the platelet-derived growth factor receptor kinase (PDGF-R), the receptor kinase for stem cell factor, c-kit, the hepatocyte growth factor receptor, c-Met, and the fibroblast growth factor receptor, FGFR3; and serine/threonine kinases such as b-RAF, mitogen-activated protein kinases (e.g., MKK6) and SAPK2β. Aberrant kinase activity has been observed in many disease states including benign and malignant proliferative disorders as well as diseases resulting from inappropriate activation of the immune and nervous systems. The novel compounds of this invention inhibit the activity of one or more protein kinases and are, therefore, expected to be useful in the treatment of kinase-mediated diseases.

Bruton's tyrosine kinase (BTK) is a non-receptor tyrosine kinase with a key role in immunoreceptor signaling (BCR, FcR, FcγR, DAP12, Dectin-1, GPVI, etc.) in a host of hematopoietic cells including B cells, platelets, mast cells, basophils, eosinophils, macrophages and neutrophils as well as osteoclasts involved in bone destruction (for reviews, see Brunner et al., 2005 Histol. Histopathol., 20:945, Mohamed et al., 2009 Immunol. Rev., 228:58). Mutations in BTK are known to lead to X-linked agammaglobulinemia (XLA) in humans and X-linked immunodeficiency (Xid) in mice, which are characterized by limited B-cell production & reduced antibody titers (Lindvall et al., 2005 Immunol. Rev., 203:200). The combined action of BTK in multiple cell types makes it an attractive target for autoimmune disease. BTK is related with sequence homology to other Tec family kinases (ITK, Tec, ETK/BMX & RLK/TXK).

In B-lymphocytes, BTK is required for B-cell development and for Ca2+ mobilization following of B-cell receptor (BCR) engagement (Khan et al., 1995 Immunity 3:283; Genevier et al., 1997 Clin. Exp. Immun., 110:286) where it is believed to downstream of Src family kinases (such as Lyn), Syk & PI3K. BTK has been shown to be important for both thymus-dependent and thymus-independent type 2 responses to antigens (Khan et al., Immunity 1995, 3:283). In mast cells, studies using BTK mouse knock-outs (Hata et al., 1998 J. Exp. Med., 187:1235; Schmidt et al., 2009 Eur. J Immun., 39:3228) indicate a role for BTK in FcsRI induced signaling, histamine release & production of cytokines such as TNF, IL-2, & IL-4. In platelets, BTK is important for signaling through the glycoprotein VI (GPVI) receptor that responds to collagen and has been shown to promote platelet aggregation and contribute to cytokine production from fibroblast-like synoviocytes (Hsu et al., 2013 Immun. Letters, 150:97). In monocytes and macrophages, the action of BTK in invoked in FcγRI induced signaling and may also have role in Toll-Like Receptor-induced cytokine responses including TLR2, TLR4, TLR8 & TLR9 (Horwood et al., 2003 J. Exp. Med., 197:1603; Horwood et al., 2006 J. Immunol., 176:3635; Perez de Diego et al., 2006 Allerg. Clin. Imm., 117:1462; Doyle et al., 2007 J. Biol. Chem., 282:36959, Hasan et al., 2007 Immunology, 123:239; Sochorava et al., 2007 Blood, 109:2553; Lee et al., 2008, J. Biol. Chem., 283:11189).

Therefore, inhibition of BTK is expected to intervene at several critical junctions of the inflammatory reactions resulting in an effective suppression of autoimmune response. As such diseases involving B-cell receptor activation, antibody-Fc receptor interactions & GPVI receptor signaling may be modulated by treatment with BTK inhibitors. BTK inhibition is likely to act on both the initiation of autoimmune disease by blocking BCR signaling and the effector phase by abrogation of FcR signaling on macrophages, neutrophils, basophils, and mast cells. Furthermore, blocking BTK would provide additional benefit via inhibition of osteoclast maturation and therefore attenuate the bone erosions & overall joint destruction associated with rheumatoid arthritis. Inhibiting BTK may be useful in treating a host of inflammatory and allergic diseases—for example (but not limited to), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), multiple sclerosis (MS) and type I hypersensitivity reactions such as allergic rhinitis, allergic conjunctivitis, atopic dermatitis, allergic asthma and systemic anaphylaxis. For a review on targeting BTK as a treatment for inflammatory disorders and autoimmunity as well as leukemias and lymphomas, see Uckun & Qazi, 2010 Expert Opin. Ther. Pat., 20:1457. Because BTK is highly expressed in cancers of the hematopoietic system & BTK-dependent signaling in believed to be disregulated there, BTK inhibitors are expected to be useful treatments for B-cell lymphomas/leukemias & other oncologic disease—for example (but not limited to) acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), non-Hodgkin's lymphoma (NHL), small lymphocytic lymphoma (SLL), and acute myeloid leukemia (for review, see Buggy & Elias 2012 Int. Rev. Immunol. 31:119). Taken together, BTK inhibitors provide a strong method to treat a host of inflammatory diseases and immunological disorders as well as hematologic cancers.

DETAILED DESCRIPTION OF THE INVENTION

Protein kinases are a broad and diverse class, of over 500 enzymes, that include oncogenes, growth factors receptors, signal transduction intermediates, apoptosis related kinases and cyclin dependent kinases. They are responsible for the transfer of a phosphate group to specific tyrosine, serine or threonine amino acid residues, and are broadly classified as tyrosine and serine/threonine kinases as a result of their substrate specificity.

The protein kinases represent a large family of proteins that play a central role in the regulation of a wide variety of cellular processes and maintenance of cellular function. A partial, non-limiting, list of these kinases include: non-receptor tyrosine kinases such as the Tec family (BTK, ITK, Tec, ETK/BMX & RLK/TXK), Janus kinase family (Jak1, Jak2, Jak3 and Tyk2); the fusion kinases, such as BCR-Abl, focal adhesion kinase (FAK), Fes, Lek and Syk; receptor tyrosine kinases such as epidermal growth factor receptor (EGFR), the platelet-derived growth factor receptor kinase (PDGF-R), the receptor kinase for stem cell factor, c-kit, the hepatocyte growth factor receptor, c-Met, and the fibroblast growth factor receptor, FGFR3; and serine/threonine kinases such as b-RAF, mitogen-activated protein kinases (e.g., MKK6) and SAPK2β. Aberrant kinase activity has been observed in many disease states including benign and malignant proliferative disorders as well as diseases resulting from inappropriate activation of the immune and nervous systems. The novel compounds of this invention inhibit the activity of one or more protein kinases and are, therefore, expected to be useful in the treatment of kinase-mediated diseases.

Bruton's tyrosine kinase (BTK) is a non-receptor tyrosine kinase with a key role in immunoreceptor signaling (BCR, FcR, FcγR, DAP12, Dectin-1, GPVI, etc.) in a host of hematopoietic cells including B cells, platelets, mast cells, basophils, eosinophils, macrophages and neutrophils as well as osteoclasts involved in bone destruction (for reviews, see Brunner et al., 2005 Histol. Histopathol., 20:945; Mohamed et al., 2009 Immunol. Rev., 228:58). Mutations in BTK are known to lead to X-linked agammaglobulinemia (XLA) in humans and X-linked immunodeficiency (Xid) in mice, which are characterized by limited B-cell production & reduced antibody titers (Lindvall et al., 2005 Immunol. Rev., 203:200). The combined action of BTK in multiple cell types makes it an attractive target for autoimmune disease. BTK is related with sequence homology to other Tec family kinases (ITK, Tec, ETK/BMX & RLK/TXK).

In B-lymphocytes, BTK is required for B-cell development and for Ca2+ mobilization following B-cell receptor (BCR) engagement (Khan et al., 1995 Immunity 3:283; Genevier et al., 1997 Clin. Exp. Immun., 110:286) where it is believed to be downstream of Src family kinases (such as Lyn), Syk & PI3K. BTK has been shown to be important for both thymus-dependent and thymus-independent type 2 responses to antigens (Khan et al., Immunity 1995; 3:283). In mast cells, studies using BTK mouse knock-outs (Hata et al., 1998 J. Exp. Med., 187:1235; Schmidt et al., 2009 Eur. J. Immun., 39:3228) indicate a role for BTK in FcsRI induced signaling, histamine release & production of cytokines such as TNF, IL-2, & IL-4. In platelets, BTK is important for signaling through the glycoprotein VI (GPVI) receptor that responds to collagen and has been shown to promote platelet aggregation and contribute to cytokine production from fibroblast-like synoviocytes (Hsu et al., 2013 Immun. Letters 150:97). In monocytes and macrophages, the action of BTK is invoked in FcγRI induced signaling and may also have role in Toll-Like Receptor-induced cytokine responses including TLR2, TLR4, TLR8 & TLR9 (Horwood et al., 2003 J. Exp. Med., 197:1603; Horwood et al., 2006 J. Immunol., 176:3635; Perez de Diego et al., 2006 Allerg. Clin. Imm., 117:1462; Doyle et al., 2007 J. Biol. Chem., 282:36959, Hasan et al., 2007 Immunology, 123:239; Sochorava et al., 2007 Blood, 109:2553; Lee et al., 2008, J. Biol. Chem., 283:11189).

Therefore, inhibition of BTK is expected to intervene at several critical junctions of the inflammatory reactions resulting in an effective suppression of autoimmune response. As such diseases involving B-cell receptor activation, antibody-Fc receptor interactions & GPVI receptor signaling may be modulated by treatment with BTK inhibitors. BTK inhibition is likely to act on both the initiation of autoimmune disease by blocking BCR signaling and the effector phase by abrogation of FcR signaling on macrophages, neutrophils, basophils, and mast cells. Furthermore, blocking BTK would provide additional benefit via inhibition of osteoclast maturation and therefore attenuate the bone erosions & overall joint destruction associated with rheumatoid arthritis. Inhibiting BTK may be useful in treating a host of inflammatory and allergic diseases—for example (but not limited to), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), multiple sclerosis (MS) and type I hypersensitivity reactions such as allergic rhinitis, allergic conjunctivitis, atopic dermatitis, allergic asthma and systemic anaphylaxis. For a review on targeting BTK as a treatment for inflammatory disorders and autoimmunity as well as leukemias and lymphomas, see Uckun & Qazi 2010 Expert Opin Ther Pat 20:1457. Because BTK is highly expressed in cancers of the hematopoietic system & BTK-dependent signaling in believed to be disregulated there, BTK inhibitors are expected to be useful treatments for B-cell lymphomas/leukemias & other oncologic disease—for example (but not limited to) acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), non-Hodgkin's lymphoma (NHL), small lymphocytic lymphoma (SLL), and acute myeloid leukemia (for review, see Buggy & Elias 2012 Int Rev Immunol. 31:119). Taken together, BTK inhibitors provide a strong method to treat a host of inflammatory diseases and immunological disorders as well as hematologic cancers.

All kinases bind a common molecule, ATP, and therefore have structurally similar binding pockets. Therefore, one of the challenges for any kinase inhibitor is that they are prone to inhibit more than one kinase due to the homology of the binding pocket. For example, staurosporine, a well characterized promiscuous kinase inhibitor, has been shown to inhibit at least 253 with a kd of <3 μM kinases from the human kinome (see Nature Biotechnology, 208, 26, p. 127). Additionally, several marketed kinase inhibitors are known to inhibit more than one intended kinase, for example Imatinib (Gleevec®) targets ABL, ARG, PDGFR-α/β and c-KIT kinases, sorafenib (Nexavar®) targets B-RAF, VEGFRs, PDGFR-α/β, FLT3 and c-KIT and sunitinib (Sutent®) targets VEGFR, PDGFR, CSF1R, FLT3 and c-KIT (Nature Reviews Drug Discovery 2011, 10, 111).

Inhibition of certain kinases in the human kinome are known to have undesired effects when used as pharmaceutical treatment. For instance, a number of kinase targets have been implicated in playing a role in the cardiotoxicity profiles for kinase inhibitors that are currently on the market. These kinases can include, but not limited to, VEGFR2, PI3K, AKT, PDGFR-α/p, AMPK, GSK3, ERKs, CDK2, Aurora, PLK, INK, CAMKII<PDK1, mTOR, LKB1, CAMKKP, MEK1/2, PKA, PKCα, RAF1, B-RAF, EGFR, ERBB2, c-Kit, ABL, ARG, JAK2, FAK, DMPK, LTK, ROCK, LKB1, LDB3, PIM, GRK2, GRK5, ASK1, and PTEN (see Nature Reviews Drug Discovery 2011, 10:111). One example from a marketed kinase inhibitor is that in clinical trials with sunitinib, patients were found to be at increased risk for hypertension (see The Lancet 2006, 368:1329; and J. Cin. Oncol. 2009, 27:3584). Subsequent research on the mechanism for the increased hypertension suggest that while PDGFR and VEGFR may be playing a role, off-target kinase inhibition, such as AMPK, may also be contributing to sunitinib's increased risk for hypertension (Curr. Hypertens. Rep. 2011, 13:436). Additionally, there is a patent application, US 2011/0212461, that has been filed that is a method for the prediction of cardiotoxicity based on the activity versus a list of kinases including CSF1R, KIT, FYN, PDGFR beta, FGR, LCK, Ephrin Receptor B2, FRK, ABL1, PDGFR1 alpha, HCK, ABL2, LYN, ZAK, YES1, MAP4K4, PKN1, BRAF, DDR2, MAP4K5 and STK24. Therefore, identification of kinase inhibitors with a selective profile Btk kinase are desirable. The compounds of this invention are selective for the inhibition of Btk over other kinases.

Many of the kinases, whether a receptor or non-receptor tyrosine kinase or a S/T kinase have been found to be involved in cellular signaling pathways involved in numerous pathogenic conditions, including immunomodulation, inflammation, or proliferative disorders such as cancer.

Many autoimmune diseases and disease associated with chronic inflammation, as well as acute responses, have been linked to excessive or unregulated production or activity of one or more cytokines.

In this invention, the following definitions are applicable:

A “therapeutically effective amount” is an amount of a compound of Formula (I) or a combination of two or more such compounds, which inhibits, totally or partially, the progression of the condition or alleviates, at least partially, one or more symptoms of the condition. A therapeutically effective amount can also be an amount which is prophylactically effective. The amount which is therapeutically effective will depend upon the patient's size and gender, the condition to be treated, the severity of the condition and the result sought. For a given patient, a therapeutically effective amount can be determined by methods known to those of skill in the art.

“Pharmaceutically acceptable salts” refers to those salts which retain the biological effectiveness and properties of the free bases and which are obtained by reaction with inorganic acids, for example, hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, and phosphoric acid or organic acids such as sulfonic acid, carboxylic acid, organic phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, citric acid, fumaric acid, maleic acid, succinic acid, benzoic acid, salicylic acid, lactic acid, tartaric acid (e.g. (+) or (−)-tartaric acid or mixtures thereof), amino acids (e.g. (+) or (−)-amino acids or mixtures thereof), and the like. These salts can be prepared by methods known to those skilled in the art.

Certain compounds of Formula (I) which have acidic substituents may exist as salts with pharmaceutically acceptable bases. The present invention includes such salts. Examples of such salts include sodium salts, potassium salts, lysine salts and arginine salts. These salts may be prepared by methods known to those skilled in the art.

Certain compounds of Formula (I) and their salts may exist in more than one crystal form and the present invention includes each crystal form and mixtures thereof.

Certain compounds of Formula (I) and their salts may also exist in the form of solvates, for example hydrates, and the present invention includes each solvate and mixtures thereof.

Certain compounds of Formula (I) may contain one or more chiral centers, and exist in different optically active forms. When compounds of Formula (I) contain one chiral center, the compounds exist in two enantiomeric forms and the present invention includes both enantiomers and mixtures of enantiomers, such as racemic mixtures. The enantiomers may be resolved by methods known to those skilled in the art, for example by formation of diastereoisomeric salts which may be separated, for example, by crystallization; formation of diastereoisomeric derivatives or complexes which may be separated, for example, by crystallization, gas-liquid or liquid chromatography; selective reaction of one enantiomer with an enantiomer-specific reagent, for example enzymatic esterification; or gas-liquid or liquid chromatography in a chiral environment, for example on a chiral support for example silica with a bound chiral ligand or in the presence of a chiral solvent. It will be appreciated that where the desired enantiomer is converted into another chemical entity by one of the separation procedures described above, a further step is required to liberate the desired enantiomeric form. Alternatively, specific enantiomers may be synthesized by asymmetric synthesis using optically active reagents, substrates, catalysts or solvents, or by converting one enantiomer into the other by asymmetric transformation.

When a compound of Formula (I) contains more than one chiral center, it may exist in diastereoisomeric forms. The diastereoisomeric compounds may be separated by methods known to those skilled in the art, for example chromatography or crystallization and the individual enantiomers may be separated as described above. The present invention includes each diastereoisomer of compounds of Formula (I) (and mixtures thereof.

The present invention includes each conformational isomer of compounds of Formula (I) and mixtures thereof.

Certain compounds of Formula (I) may exist in zwitterionic form and the present invention includes each zwitterionic form of compounds of Formula (I) (and mixtures thereof.

As used herein the term “pro-drug” refers to an agent which is converted into the parent drug in vivo by some physiological chemical process (e.g., a prodrug on being brought to the physiological pH is converted to the desired drug form). Pro-drugs are often useful because, in some situations, they may be easier to administer than the parent drug. They may, for instance, be bioavailable by oral administration whereas the parent drug is not. The pro-drug may also have improved solubility in pharmacological compositions over the parent drug. An example, without limitation, of a pro-drug would be a compound of the present invention wherein it is administered as an ester (the “pro-drug”) to facilitate transmittal across a cell membrane where water solubility is not beneficial, but then it is metabolically hydrolyzed to the carboxylic acid once inside the cell where water solubility is beneficial.

Pro-drugs have many useful properties. For example, a pro-drug may be more water soluble than the ultimate drug, thereby facilitating intravenous administration of the drug. A pro-drug may also have a higher level of oral bioavailability than the ultimate drug. After administration, the prodrug is enzymatically or chemically cleaved to deliver the ultimate drug in the blood or tissue.

Exemplary pro-drugs upon cleavage release the corresponding free acid, and such hydrolyzable ester-forming residues of the compounds of this invention include but are not limited to carboxylic acid substituents wherein the free hydrogen is replaced by (C1-C4)alkyl, (C1-C12)alkanoyloxymethyl, (C4-C9)1-(alkanoyloxy)ethyl, 1-methyl-1-(alkanoyloxy)-ethyl having from 5 to 10 carbon atoms, alkoxycarbonyloxymethyl having from 3 to 6 carbon atoms, 1-(alkoxycarbonyloxy)ethyl having from 4 to 7 carbon atoms, 1-methyl-1-(alkoxycarbonyloxy)ethyl having from 5 to 8 carbon atoms, N-(alkoxycarbonyl)aminomethyl having from 3 to 9 carbon atoms, 1-(N-(alkoxycarbonyl)amino)ethyl having from 4 to 10 carbon atoms, 3-phthalidyl, 4-crotonolactonyl, gamma-butyrolacton-4-yl, di-N,N—(C1-C2)alkylamino(C2-C3)alkyl (such as β-dimethylaminoethyl), carbamoyl-(C1-C2)alkyl, NN-di(C1-C2)-alkylcarbamoyl-(C1-C2)alkyl and piperidino-, pyrrolidino- or morpholino(C2-C3)alkyl.

Other exemplary pro-drugs release an alcohol of Formula (I) wherein the free hydrogen of the hydroxyl substituent (e.g., R1 contains hydroxyl) is replaced by (C1-C6)alkanoyloxymethyl, 1-((C1-C6)alkanoyloxy)ethyl, 1-methyl-1-((C1-C6)alkanoyloxy)ethyl, (C1-C12)alkoxycarbonyloxymethyl, N—(C1-C6)alkoxycarbonylamino-methyl, succinoyl, (C1-C6)alkanoyl, α-amino(C2-C4)alkanoyl, arylactyl and α-aminoacyl, or α-aminoacyl-α-aminoacyl wherein said α-aminoacyl moieties are independently any of the naturally occurring L-amino acids found in proteins, P(O)(OH)2, —P(O)(O(C1-C6)alkyl)2 or glycosyl (the radical resulting from detachment of the hydroxyl of the hemiacetal of a carbohydrate).

The term “kit” as used herein refers to a packaged product comprising components with which to administer a compound of Formula (I) of the invention for treatment of an autoimmune disorder. The kit preferably comprises a box or container that holds the components of the kit. The box or container is affixed with a label or a Food and Drug Administration approved protocol. The box or container holds components of the invention which are preferably contained within plastic, polyethylene, polypropylene, ethylene, or propylene vessels. The vessels can be capped-tubes or bottles. The kit can also include instructions for administering a compound of Formula (I).

One or more compounds of this invention can be administered to a human patient by themselves or in pharmaceutical compositions where they are mixed with biologically suitable carriers or excipient(s) at doses to treat or ameliorate a disease or condition as described herein. Mixtures of these compounds can also be administered to the patient as a simple mixture or in suitable formulated pharmaceutical compositions. A therapeutically effective dose refers to that amount of the compound or compounds sufficient to result in the prevention or attenuation of a disease or condition as described herein. Techniques for formulation and administration of the compounds of the instant application may be found in references well known to one of ordinary skill in the art, such as “Remington's Pharmaceutical Sciences,” Mack Publishing Co., Easton, Pa., latest edition.

Suitable routes of administration may, for example, include oral, eyedrop, rectal, transmucosal, topical, or intestinal administration; parenteral delivery, including intramuscular, subcutaneous, intramedullary injections, as well as intrathecal, direct intraventricular, intravenous, intraperitoneal, intranasal, or intraocular injections.

Alternatively, one may administer the compound in a local rather than a systemic manner, for example, via injection of the compound directly into an edematous site, often in a depot or sustained release formulation.

Furthermore, one may administer the drug in a targeted drug delivery system, for example, in a liposome coated with endothelial cell-specific antibody.

The pharmaceutical compositions of the present invention may be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or lyophilizing processes.

Pharmaceutical compositions for use in accordance with the present invention thus may be formulated in a conventional manner using one or more physiologically acceptable carriers comprising excipients and auxiliaries which facilitate processing of the active compounds into preparations which can be used pharmaceutically. Proper formulation is dependent upon the route of administration chosen.

For injection, the agents of the invention may be formulated in aqueous solutions, preferably in physiologically compatible buffers such as Hanks' solution, Ringer's solution, or physiological saline buffer. For transmucosal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art.

For oral administration, the compounds can be formulated readily by combining the active compounds with pharmaceutically acceptable carriers well known in the art. Such carriers enable the compounds of the invention to be formulated as tablets, pills, dragees, capsules, liquids, gels, syrups, slurries, suspensions and the like, for oral ingestion by a patient to be treated. Pharmaceutical preparations for oral use can be obtained by combining the active compound with a solid excipient, optionally grinding a resulting mixture, and processing the mixture of granules, after adding suitable auxiliaries, if desired, to obtain tablets or dragee cores. Suitable excipients are, in particular, fillers such as sugars, including lactose, sucrose, mannitol, or sorbitol; cellulose preparations such as, for example, maize starch, wheat starch, rice starch, potato starch, gelatin, gum tragacanth, methyl cellulose, hydroxypropylmethyl-cellulose, sodium carboxymethylcellulose, and/or polyvinylpyrrolidone (PVP). If desired, disintegrating agents may be added, such as the cross-linked polyvinyl pyrrolidone, agar, or alginic acid or a salt thereof such as sodium alginate.

Dragee cores are provided with suitable coatings. For this purpose, concentrated sugar solutions may be used, which may optionally contain gum arabic, talc, polyvinyl pyrrolidone, carbopol gel, polyethylene glycol, and/or titanium dioxide, lacquer solutions, and suitable organic solvents or solvent mixtures. Dyestuffs or pigments may be added to the tablets or dragee coatings for identification or to characterize different combinations of active compound doses.

Pharmaceutical preparations that can be used orally include push-fit capsules made of gelatin, as well as soft, sealed capsules made of gelatin and a plasticizer, such as glycerol or sorbitol. The push-fit capsules can contain the active ingredients in admixture with filler such as lactose, binders such as starches, and/or lubricants such as talc or magnesium stearate and, optionally, stabilizers. In soft capsules, the active compounds may be dissolved or suspended in suitable liquids, such as fatty oils, liquid paraffin, or liquid polyethylene glycols. In addition, stabilizers may be added. All formulations for oral administration should be in dosages suitable for such administration.

For buccal administration, the compositions may take the form of tablets or lozenges formulated in conventional manner.

For administration by inhalation, the compounds for use according to the present invention are conveniently delivered in the form of an aerosol spray presentation from pressurized packs or a nebuliser, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide or other suitable gas. In the case of pressurized aerosol the dosage unit may be determined by providing a valve to deliver a metered amount. Capsules and cartridges of e.g. gelatin for use in an inhaler or insufflator may be formulated containing a powder mix of the compound and a suitable powder base such as lactose or starch.

The compounds can be formulated for parenteral administration by injection, e.g. bolus injection or continuous infusion. Formulations for injection may be presented in unit dosage form, e.g. in ampoules or in multi-dose containers, with an added preservative. The compositions may take such forms as suspensions, solutions or emulsions in oily or aqueous vehicles, and may contain formulatory agents such as suspending, stabilizing and/or dispersing agents.

Pharmaceutical formulations for parenteral administration include aqueous solutions of the active compounds in water-soluble form. Additionally, suspensions of the active compounds may be prepared as appropriate oily injection suspensions. Suitable lipophilic solvents or vehicles include fatty oils such as sesame oil, or synthetic fatty acid esters, such as ethyl oleate or triglycerides, or liposomes. Aqueous injection suspensions may contain substances which increase the viscosity of the suspension, such as sodium carboxymethyl cellulose, sorbitol, or dextran. Optionally, the suspension may also contain suitable stabilizers or agents which increase the solubility of the compounds to allow for the preparation of highly concentrated solutions.

Alternatively, the active ingredient may be in powder form for constitution with a suitable vehicle, e.g., sterile pyrogen-free water, before use.

The compounds may also be formulated in rectal compositions such as suppositories or retention enemas, e.g., containing conventional suppository bases such as cocoa butter or other glycerides.

In addition to the formulations described previously, the compounds may also be formulated as a depot preparation. Such long acting formulations may be administered by implantation (for example subcutaneously or intramuscularly or by intramuscular injection). Thus, for example, the compounds may be formulated with suitable polymeric or hydrophobic materials (for example as an emulsion in an acceptable oil) or ion exchange resins, or as sparingly soluble derivatives, for example, as a sparingly soluble salt.

An example of a pharmaceutical carrier for the hydrophobic compounds of the invention is a cosolvent system comprising benzyl alcohol, a nonpolar surfactant, a water-miscible organic polymer, and an aqueous phase. The cosolvent system may be the VPD co-solvent system. VPD is a solution of 3% w/v benzyl alcohol, 8% w/v of the nonpolar surfactant polysorbate 80, and 65% w/v polyethylene glycol 300, made up to volume in absolute ethanol. The VPD co-solvent system (VPD:5W) consists of VPD diluted 1:1 with a 5% dextrose in water solution. This co-solvent system dissolves hydrophobic compounds well, and itself produces low toxicity upon systemic administration. Naturally, the proportions of a co-solvent system may be varied considerably without destroying its solubility and toxicity characteristics. Furthermore, the identity of the co-solvent components may be varied: for example, other low-toxicity nonpolar surfactants may be used instead of polysorbate 80; the fraction size of polyethylene glycol may be varied; other biocompatible polymers may replace polyethylene glycol, e.g. polyvinyl pyrrolidone; and other sugars or polysaccharides may substitute for dextrose.

Alternatively, other delivery systems for hydrophobic pharmaceutical compounds may be employed. Liposomes and emulsions are well known examples of delivery vehicles or carriers for hydrophobic drugs. Certain organic solvents such as dimethysulfoxide also may be employed, although usually at the cost of greater toxicity. Additionally, the compounds may be delivered using a sustained-release system, such as semipermeable matrices of solid hydrophobic polymers containing the therapeutic agent. Various sustained-release materials have been established and are well known by those skilled in the art. Sustained-release capsules may, depending on their chemical nature, release the compounds for a few weeks up to over 100 days. Depending on the chemical nature and the biological stability of the therapeutic reagent, additional strategies for protein stabilization may be employed.

The pharmaceutical compositions also may comprise suitable solid or gel phase carriers or excipients. Examples of such carriers or excipients include but are not limited to calcium carbonate, calcium phosphate, various sugars, starches, cellulose derivatives, gelatin, and polymers such as polyethylene glycols.

Many of the compounds of the invention may be provided as salts with pharmaceutically compatible counter ions. Pharmaceutically compatible salts may be formed with many acids, including but not limited to hydrochloric, sulfuric, acetic, lactic, tartaric, malic, succinic, etc. Salts tend to be more soluble in aqueous or other protonic solvents than are the corresponding free base forms.

Pharmaceutical compositions suitable for use in the present invention include compositions wherein the active ingredients are contained in an effective amount to achieve its intended purpose. More specifically, a therapeutically effective amount means an amount effective to prevent development of or to alleviate the existing symptoms of the subject being treated. Determination of the effective amounts is well within the capability of those skilled in the art.

For any compound used in a method of the present invention, the therapeutically effective dose can be estimated initially from cellular assays. For example, a dose can be formulated in cellular and animal models to achieve a circulating concentration range that includes the IC50 as determined in cellular assays (e.g., the concentration of the test compound which achieves a half-maximal inhibition of a given protein kinase activity). In some cases it is appropriate to determine the IC50 in the presence of 3 to 5% serum albumin since such a determination approximates the binding effects of plasma protein on the compound. Such information can be used to more accurately determine useful doses in humans. Further, the most preferred compounds for systemic administration effectively inhibit protein kinase signaling in intact cells at levels that are safely achievable in plasma.

A therapeutically effective dose refers to that amount of the compound that results in amelioration of symptoms in a patient. Toxicity and therapeutic efficacy of such compounds can be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the maximum tolerated dose (MTD) and the EDo (effective dose for 50% maximal response). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio between MTD and ED50. Compounds which exhibit high therapeutic indices are preferred. The data obtained from these cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the EDo with little or no toxicity. The dosage may vary within this range depending upon the dosage form employed and the route of administration utilized. The exact formulation, route of administration and dosage can be chosen by the individual physician in view of the patient's condition (see, e.g., Fingl et al., 1975, in The Pharmacological Basis of Therapeutics, Ch. 1, p. 1). In the treatment of crises, the administration of an acute bolus or an infusion approaching the MTD may be required to obtain a rapid response.

Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the kinase modulating effects, or minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vitro data; e.g. the concentration necessary to achieve 50-90% inhibition of protein kinase using the assays described herein. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations.

Dosage intervals can also be determined using the MEC value. Compounds should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90% until the desired amelioration of symptoms is achieved. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.

The amount of composition administered will, of course, be dependent on the subject being treated, on the subject's weight, the severity of the affliction, the manner of administration and the judgment of the prescribing physician.

The compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active ingredient. The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. Compositions comprising a compound of the invention formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labelled for treatment of an indicated condition.

In some formulations it may be beneficial to use the compounds of the present invention in the form of particles of very small size, for example as obtained by fluid energy milling.

The use of compounds of the present invention in the manufacture of pharmaceutical compositions is illustrated by the following description. In this description the term “active compound” denotes any compound of the invention but particularly any compound which is the final product of one of the following Examples.

a) Capsules

In the preparation of capsules, 10 parts by weight of active compound and 240 parts by weight of lactose can be de-aggregated and blended. The mixture can be filled into hard gelatin capsules, each capsule containing a unit dose or part of a unit dose of active compound.

b) Tablets

Tablets can be prepared, for example, from the following ingredients.

Parts by weight

Active compound 10 Lactose 190 Maize starch 22 Polyvinylpyrrolidone 10 Magnesium stearate 3

The active compound, the lactose and some of the starch can be de-aggregated, blended and the resulting mixture can be granulated with a solution of the polyvinylpyrrolidone in ethanol. The dry granulate can be blended with the magnesium stearate and the rest of the starch. The mixture is then compressed in a tabletting machine to give tablets each containing a unit dose or a part of a unit dose of active compound.

c) Enteric Coated Tablets

Tablets can be prepared by the method described in (b) above. The tablets can be enteric coated in a conventional manner using a solution of 20% cellulose acetate phthalate and 3% diethyl phthalate in ethanol:dichloromethane (1:1).

d) Suppositories

In the preparation of suppositories, for example, 100 parts by weight of active compound can be incorporated in 1300 parts by weight of triglyceride suppository base and the mixture formed into suppositories each containing a therapeutically effective amount of active ingredient.

In the compositions of the present invention the active compound may, if desired, be associated with other compatible pharmacologically active ingredients. For example, the compounds of this invention can be administered in combination with another therapeutic agent that is known to treat a disease or condition described herein. For example, with one or more additional pharmaceutical agents that inhibit or prevent the production of VEGF or angiopoietins, attenuate intracellular responses to VEGF or angiopoietins, block intracellular signal transduction, inhibit vascular hyperpermeability, reduce inflammation, or inhibit or prevent the formation of edema or neovascularization. The compounds of the invention can be administered prior to, subsequent to or simultaneously with the additional pharmaceutical agent, whichever course of administration is appropriate. The additional pharmaceutical agents include, but are not limited to, anti-edemic steroids, NSAIDS, ras inhibitors, anti-TNF agents, anti-IL1 agents, antihistamines, PAF-antagonists, COX-1 inhibitors, COX-2 inhibitors, NO synthase inhibitors, Akt/PTB inhibitors, IGF-1R inhibitors, PKC inhibitors, PI3 kinase inhibitors, calcineurin inhibitors and immunosuppressants. The compounds of the invention and the additional pharmaceutical agents act either additively or synergistically. Thus, the administration of such a combination of substances that inhibit angiogenesis, vascular hyperpermeability and/or inhibit the formation of edema can provide greater relief from the deletrious effects of a hyperproliferative disorder, angiogenesis, vascular hyperpermeability or edema than the administration of either substance alone. In the treatment of malignant disorders combinations with antiproliferative or cytotoxic chemotherapies or radiation are included in the scope of the present invention.

The present invention also comprises the use of a compound of Formula (I) as a medicament.

A further aspect of the present invention provides the use of a compound of Formula (I) or a salt thereof in the manufacture of a medicament for treating vascular hyperpermeability, angiogenesis-dependent disorders, proliferative diseases and/or disorders of the immune system in mammals, particularly human beings.

The present invention also provides a method of treating vascular hyperpermeability, inappropriate neovascularization, proliferative diseases and/or disorders of the immune system which comprises the administration of a therapeutically effective amount of a compound of Formula (I) to a mammal, particularly a human being, in need thereof.

General Synthetic Schemes

Compounds of the invention may be prepared using the synthetic transformations illustrated in Schemes I-XVIII. Starting materials are commercially available, may be prepared by the procedures described herein, by literature procedures, or by procedures that would be well known to one skilled in the art of organic chemistry.

Methods for preparing 1H-indole-7-carboxamide compounds 9 of the invention are illustrated in Scheme I. In Scheme I, step a, commercially available 4-bromo-2-nitrobenzoic acid 1 is reacted with vinylmagnesium bromide via a Bartoli indole synthesis using methods known to one skilled in the art (for example Preparation #1, step A) to give indole 2. Indole 2 can be alkylated with methyl iodide (Scheme I, step b) to provide methyl 1H-indole-7-carboxylate 3 using methods known to one skilled in the art (for example Preparation #1, step B). The resulting indole 3 may be tosyl (Ts) protected (Scheme I, step c) using conditions such as those described in Preparation #1, step C or those described in Greene, T. W. and Wuts, P. G. M. “Protective Groups in Organic Synthesis, 3rd Edition”, 1999, Wiley-Interscience; Larock, R. C. “Comprehensive Organic Transformations: A Guide to Functional Group Preparations, 2nd edition”, 1999, Wiley-VCH. In step d, directed lithiation of methyl 4-bromo-1-tosyl-1H-indole-7-carboxylate 4 followed by trapping of the anion with iodine yields methyl 4-bromo-2-iodo-1H-indole-7-carboxylates 5 using conditions such as those described in Preparation #1 step D. Tosyl protected methyl 4-bromo-2-iodo-1H-indole-7-carboxylates 5 may be hydrolyzed and deprotected under aqueous base conditions in one step e to give 4-bromo-2-iodo-1H-indole-7-carboxylic acid 6 using conditions such as those described in Preparation #1, step E or known to one skilled in the art (for example, the books from Larock, R. C. or Greene, T. W. and Wuts, P. G. M. referenced above). In step f, 4-bromo-2-iodo-1H-indole-7-carboxylic acid 6 may be converted to a primary amide 7 as shown using conditions such as those described in General Procedure D. The 4-bromo-2-iodo-1H-indole-7-carboxamide 7 may undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Suzuki or Stille coupling reactions such as those described in General Procedure A and Example #22, step A. Alternatively, in step i, the tosyl protected indoles 5 may undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Suzuki or Stille coupling reactions described by General Procedure A (for example Preparation #15 step A). Hydrolysis of esters 10 gives acids 11 (Scheme I, step j) using well known conditions such as those described in Preparation #15, step B or General Procedure C. In step k, carboxylic acid 11 may be coverted to primary amides 12 as shown using conditions such as those described in General Procedure D. Removal of the sulfonamide protecting group of indoles 12 may be accomplished using conditions such as those described in General Procedure N, or by methods known to one skilled in the art (for example, Larock, R. C. or Greene, T. W. and Wuts, P. G. M. referenced above) to give indoles 8 (Scheme I, step 1). Indoles 8 are reacted with a boronate ester or boronic acid, either commercially available or prepared by methods known to one skilled in the art (see, for example, Larock, R. C. “Comprehensive Organic Transformations: A Guide to Functional Group Preparations, 2nd edition”, 1999, Wiley-VCH or General Procedure P), using Suzuki coupling conditions, such as those described by General Procedure A, to give 1H-indole-7-carboxamide compounds 9. Alternatively, in step h, indoles 8 may undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Buchwald or Negishi coupling conditions as described by General Procedures T and U. Further functionalization of the R″ group in indoles 9 can be performed, if desired, using reactions known to one skilled in the art (for example, Larock, R. C. referenced above). For example, indoles 9 containing a double bond may be reduced to saturated systems using hydrogenation conditions such as those described in General Procedure L. Ethers can be prepared from indoles 9 containing an alcohol using condition such as those described in General Procedure Q. In addition amides, ureas, sulfonamides, aryl amines, heteroaryl amines, or sulfonyl ureas can be prepared from indoles 9 containing a primary or secondary amine (for example General Procedures D, E, I, H, and J). Also, deprotection of indoles 9 containing a protecting group in either R′ or R″ can be performed using conditions such as those described in Greene, T. W. and Wuts, P. G. M. referenced above or in General Procedures G, M, or N. For example, for R″ containing a TBDMS-protected alcohol, the protecting group can be removed to yield an unprotected alcohol (for example General Procedure M) and the deprotected compounds 9 may then be reacted further as described above. Alternatively, compound 4 may first undergo a coupling reaction in step m, including but not limited to, such as Suzuki, Buchwald, or Negishi using conditions as described b General Procedures A, T and U to give compounds 107 followed by an iodination reaction as illustrated in General Procedure Y to give compounds 108 (step n). Indoles 108 may undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Suzuki or Stille coupling reactions such as those described in General Procedure A to give compounds 109.

C. referenced above, General Procedure A, and Preparation #10, step C. Hydrolysis of esters 14 gives acids 15 (step c) using well known conditions such as those described in Preparation #10, step D, or General Procedure C. Indole carboxylic acids 15 may be converted to primary amides 16 as shown using conditions such as those described in General Procedure D.

Methods for preparing 7-chlorothiazolo[5,4-c]pyridine-4-carboxamides 87 of the invention are illustrated in Scheme XV.

This intermediate is reacted with a boronate or boronic acid via a Suzuki reaction in step b, using conditions such as those illustrated in Preparation #46, step B. Intermediate 80 is hydrolyzed to give an acid as shown in Preparation #46, step B (step c). In step d, the acid is converted to an acyl azide via in situ formation of an acyl chloride using standard conditions such as those described Preparation #46, step D or WO 2012/035039. The acyl azide intermediate can then undergo a Curtius rearrangement and cyclize to give a pyridone 83 in step e, under high temperatures (For example, Preparation #46, step E or WO 2012/035039). On treatment with POCl3, in step f, pyridine-2-chloride is formed (for example, Preparation #46, step F or WO 2012/035039), which can subsequently be treated with NCS in step g, to afford a 4-bromo-7-chlorothiazolo[5,4-c]pyridine intermediate 85, as illustrated in Preparation #46, step G. Conversion of the bromo group in 85 to a cyano functionality is performed via Pd-catalyzed cyanation reaction and subsequent hydrolysis of the cyano group yields a 7-chlorothiazolo[5,4-c]pyridine-4-carboxamide as illustrated in Preparation #46, step H.

The tosylated intermediate 90 is then oxidized (step b) using conditions such as those described in General Procedure AC to give an N-oxide intermediate 91. In step c the material is halogenated as illustrated in Preparation #45, step C, followed by hydrolysis using a base, to both remove the tosyl group and hydrolyze the ester to an acid using conditions such as those described in General Procedure X. The acid can then undergo a standard amine coupling reaction as illustrated in General Procedure D, to give the amide in step e. The pyrrolo[3,2-c]pyridine 94 may undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Suzuki, Buchwald, or Negishi coupling conditions as described by General Procedures A, T and U to give compounds 39. Further functionalization of the R′ group in pyrrolo[3,2-c]pyridines 39 can be performed, if desired, using reactions known to one skilled in the art (for example, Larock, R. C. referenced above). For example, pyrrolo[3,2-c]pyridines 39 containing a double bond may be reduced to saturated systems using hydrogenation conditions such as those described in General Procedure L. Ethers can be prepared from indoles 39 containing an alcohol using condition such as those described in General Procedure Q. In addition amides, ureas, sulfonamides, aryl amines, heteroaryl amines, or sulfonyl ureas can be prepared from indoles 39 containing a primary or secondary amine (for example General Procedures D, E, I, H, and J). Also, deprotection of indoles 39 containing a protecting group in R′ can be performed using conditions such as those described in Greene, T. W. and Wuts, P. G. M. referenced above or in General Procedures G, M, or N. For example, for R″ containing a TBDMS-protected alcohol, the protecting group can be removed to yield an unprotected alcohol (for example General Procedure M) and the deprotected compounds 39 may then be reacted further as described above.

A third alternative to routes shown in schemes VIII and XVI for the preparation of 1H-pyrrolo[3,2-c]pyridine-7-carboxamides 39 is shown in scheme XVII. In step a, (4-methoxyphenyl)methanamine is treated with dimethyl 3-oxopentanedioate to give intermediate 96, which is not isolated. In step b, it is cyclized in situ via treatment with chloroacetaldehyde using conditions such as those illustrated in Preparation #37, step A or WO2005121140. De-protonation of the acidic hydrogen of 97 and reaction with methylformate, in step c, is accomplished using methods known to one skilled in the art (for example Preparation #37, step B, or WO 2005121140) to give intermediate 98. In step d, cyclization of intermediate 98 is performed using conditions such as those illustrated in Preparation #37, step C or WO 2005121140 to give the pyridinone intermediate 99. Subsequent aromatization and halogenation of pyridinone intermediate 99 in step e is done using well known conditions (for example Preparation #37, step D or WO 2005121140) to give pyrrolo[3,2-c]pyridine 100. Hydrolysis of the ester functionality in 100 gives acid 93 (step f) using standard conditions such as those described in General Procedure C. The acid can then undergo an amine coupling reaction as illustrated in General Procedure D, to give the amide in step e. The pyrrolo[3,2-c]pyridine 94 may undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Suzuki, Buchwald, or Negishi coupling conditions as described by General Procedures A, T and U to give compounds 39. Further functionalization of the R′ group in pyrrolo[3,2-c]pyridines 39 can be performed, if desired, using reactions known to one skilled in the art (for example, Larock, R. C. referenced above). For example, pyrrolo[3,2-c]pyridines 39 containing a double bond may be reduced to saturated systems using hydrogenation conditions such as those described in General Procedure L. Ethers can be prepared from indoles 39 containing an alcohol using condition such as those described in General Procedure Q. In addition amides, ureas, sulfonamides, aryl amines, heteroaryl amines, or sulfonyl ureas can be prepared from indoles 39 containing a primary or secondary amine (for example General Procedures D, E, I, H, and J). Also, deprotection of indoles 39 containing a protecting group in R′ can be performed using conditions such as those described in Greene, T. W. and Wuts, P. G. M. referenced above or in General Procedures G, M, or N. For example, for R″ containing a TBDMS-protected alcohol, the protecting group can be removed to yield an unprotected alcohol (for example General Procedure M) and the deprotected compounds 39 may then be reacted further as described above.

Alternative methods for preparing 1H-pyrrolo[2,3-c]pyridine-7-carboxamides 44 of the invention are illustrated in Scheme XVIII. 4-Bromo-1H-pyrrolo[2,3-c]pyridine 101 is oxidized to the N-oxide intermediate using methods known to one skilled in the art (for example General Procedure AC). Cyanation of the N-oxide 102 in step b is accomplished using conditions such as those illustrated in General Procedure AD to give the carbonitrile 103. The carbonitrile 103 may undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Suzuki, Buchwald, or Negishi coupling conditions as described by General Procedures A, T and U to give pyrrolo[2,3-c]pyridines 106. Subsequent hydrolysis of pyrrolo[2,3-c]pyridines 106 in step f, using standard conditions (for example General Procedure O) will yield compounds 44. Alternatively the carbonitrile 103 may first be hydrolyzed as shown in in step c to give the amide 104 when subjected to known conditions (for example General Procedure O). The amide 104 may then undergo a variety of reactions known to one skilled in the art (for example, Larock, R. C. referenced above) including, but not limited to, Suzuki, Buchwald, or Negishi coupling conditions as described by General Procedures A, T and U to give compounds 44. Further functionalization of the R′ group in pyrrolo[2,3-c]pyridines 44 can be performed, if desired, using reactions known to one skilled in the art (for example, Larock, R. C. referenced above). For example, pyrrolo[2,3-c]pyridines 44 containing a double bond may be reduced to saturated systems using hydrogenation conditions such as those described in General Procedure L. Ethers can be prepared from pyrrolo[2,3-c]pyridines 44 containing an alcohol using condition such as those described in General Procedure Q. In addition amides, ureas, sulfonamides, aryl amines, heteroaryl amines, or sulfonyl ureas can be prepared from pyrrolo[2,3-c]pyridines 44 containing a primary or secondary amine (for example General Procedures D, E, I, H, and J). Also, deprotection of pyrrolo[2,3-c]pyridines 44 containing a protecting group in R′ can be performed using conditions such as those described in Greene, T. W. and Wuts, P. G. M. referenced above or in General Procedures G, M, or N. For example, for R″ containing a TBDMS-protected alcohol, the protecting group can be removed to yield an unprotected alcohol (for example General Procedure M) and the deprotected compounds 44 may then be reacted further as described above.

If desired, chiral separation of any of the chiral compounds in Schemes I-XVIII may be done using methods known to one skilled in the art such as chiral preparative HPLC, chiral SFC or crystallization of diastereomeric salts.

The following examples are ordered according to the final general procedure used in their Preparation. The synthetic routes to any novel intermediates are detailed by sequentially listing the general procedure (letter codes) in parentheses after their name with additional reactants or reagents as appropriate.

In Vitro BTK Kinase Activity Measured by Time-Resolved Fluorescence Resonance Energy Transfer

(trFRET) The in-house BTK corresponds to recombinant human catalytic domain (aa 393-659), which was expressed in SF9 cells with an N-terminal his tag and purified by immobilized metal affinity chromatography. BTK was mixed with peptide substrate (biotin-TYRI, Sequence: Biotin-(Ahx)-GAEEEIYAAFFA-COOH, 0.2 μM final) at varying inhibitor concentrations in reaction buffer: 50 mM MOPSO pH 6.5, 10 mM MgCl2, 2 mM MnCl2, 2.5 mM DTT, 0.01% BSA, 0.1 mM Na3VO4 and 0.001 mM ATP. After about 60 min incubation at room temperature, the reaction was quenched by addition of EDTA (final concentration: 100 mM) and developed by addition of detection reagents (final approximate concentrations: 30 mM HEPES pH 7.0, 0.06% BSA, 0.006% Tween-20, 0.24 M KF, 80 ng/mL PT66K (europium labeled anti-phosphotyrosine antibody cat #61T66KLB Cisbio, Bedford, Mass.) and 0.6 g/mL SAXL (Phycolink streptavidin-allophycocyanin acceptor, cat #PJ25S, Prozyme, San Leandro, Calif.). The developed reaction was incubated in the dark for about 60 min at room temperature, then read via a time-resolved fluorescence detector (Rubystar, BMG) using a 337 nm laser for excitation and monitoring emission wavelength at 665 nm. Within the linear range of the assay, the observed signal at 665 nm was directly related to phosphorylated product and can be used to calculate the IC50 values.

For the purpose of the Tables and Examples below, the Btk IC50 of each compound is expressed as follows: A=a compound with IC50 less than 0.1 μM, B=a compound with IC50 within the range of 0.1 μM to 1 μM, and C=a compound with a Btk IC50 within the range of 1 μM to 10 M.

General Procedure C: Hydrolysis of an Ester to a Carboxylic Acid

To a flask containing an ester (preferably 1 equiv) either neat or in an organic solvent (such as 1,4-dioxane, MeOH, or THF/MeOH, preferably 1,4-dioxane) is added an aqueous base (such as aqueous NaOH or LiOH; 1-10 equiv, preferably 2-6 equiv). The mixture is stirred at about 0 to 100° C. (preferably about 25 to 60° C.) for about 1 to 48 h (preferably about 4 to 24 h). The organic solvent is optionally be concentrated in vacuo. The mixture is then acidified by the addition of a suitable aqueous acid (such as aqueous HCl). If a precipitate forms, it may be collected via filtration to give product. The mixture or the filtrate if the solid is not product may optionally be concentrated in vacuo to give the target compound as a carboxylate salt. Alternatively, the mixture is optionally filtered through a media (such as silica gel or Celite®) which is rinsed with an appropriate solvent (such as EtOAc, 1,4-dioxane, THF, MeCN, DCM, Et2O, MeOH, EtOH) and then optionally concentrated in vacuo to give a residue as the target compound. Either the residue or the solution may be optionally partitioned between water and an organic solvent (such as EtOAc, Et2O or DCM). The organic layer is isolated and may optionally be washed in no particular order with water and/or aqueous solutions containing an acid (such as HCl, AcOH or NH4Cl) and/or aqueous solutions containing a base (such as NaHCO3, Na2CO3, NaOH, KOH or NH4OH) and/or aqueous solutions containing an inorganic salt (such as NaCl, Na2SO3 or Na2S2O3). The organic solution may then be optionally dried with a drying agent (such as anhydrous MgSO4 or Na2SO4), filtered and concentrated in vacuo to give the target compound.
