  • Publication number: 20230028651
    Abstract: A manufacturing process to a bis-mesylate salt 1b of the pan-RAF inhibitor 4-amino-n-(1-((3-chloro-2-fluorophenyl)amino)-6-methylisoquinolin-5-yl)thieno[3,2-d]pyrimidine-7-carboxamide. The process features a number of efficient key reactions, including a robust and scalable Pd-catalyzed carbonylation reaction to generate thienopyrimidine 2 and a highly chemoselective PtN/C-catalyzed nitro group reduction to access penultimate intermediate 7. The final amide coupling of 7 and 2 was accomplished by a mild and safe protocol employing N,N,N?,N?-tetramethylchloroformamidinium hexafluorophosphate (TCFH) as the coupling reagent, to produce a 1:1 adduct of the freebase and THF. The adduct afforded compound 1b with excellent yield, purity, and form stability on a multikilogram production scale after reaction with MsOH and recrystallization. The methods are able to produce a compound having upwards of 95% purity.

  • Patent number: 10011559
    Abstract: This invention provides a convenient method for converting oximes into enamides. The process does not require the use of metallic reagents. Accordingly, it produces the desired compounds without the concomitant production of a large volume of metallic waste. The enamides are useful precursors to amides and amines. The invention provides a process to convert a prochiral enamide into the corresponding chiral amide. In an exemplary process, a chiral amino center is introduced during hydrogenation through the use of a chiral hydrogenation catalyst. In selected embodiments, the invention provides methods of preparing amides and amines that include the 1,2,3,4-tetrahydro-N-alkyl-1-naphthalenamine or 1,2,3,4-tetrahydro-1-naphthalenamine substructure.

  • Publication number: 20140315910
    Abstract: One aspect of the present invention relates to pharmaceutical compositions containing two or more active agents that when taken together can be used to treat, e.g., menopause, mood disorders, anxiety disorders, or cognitive disorders. The first component of the pharmaceutical composition is a sedative eszopiclone. The second component of the pharmaceutical composition is trans 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-N-methyl-1-napthalenamine or trans 4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-napthalenamine. The present invention also relates to a method of treating menopause, perimenopause, mood disorders, anxiety disorders, and cognitive disorders.
