  • Publication number: 20110201612
    Abstract: The invention relates to compositions comprising 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)-N-benzylacetamide and its mesylate and dihydrochloride salts. The invention provides an efficient process for the synthesis of 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)-N-benzylacetamide and its mesylate and dihydrochloride salts and methods for modulating one or more components of a kinase cascade using the compositions of the invention. The present invention also provides a novel polymorph of the mesylate salt of 2-(5-(4-(2-morpholinoethoxy)phenyl)pyridin-2-yl)-N-benzylacetamide (Form A), characterized by a unique X-ray diffraction pattern and Differential Scanning Calorimetry profile, as well as a unique crystalline structure.

  • Patent number: 7812050
    Abstract: Provided herein is a new form of 3-fluoro-7-(2,2,2-trifluoroethoxy)phenoxathin 10,10-dioxide, which demonstrates higher stability relative to other forms of 3-fluoro-7-(2,2,2-trifluoroethoxy)phenoxathiin-10,10-dioxide. In particular, this new form affords less dosage critical administration of 3-fluoro-7-(2,2,2-trifluoroethoxy)phenoxathin 10,10-dioxide relative to other forms. The new solid form of 3-fluoro-7-(2,2,2-trifluoroethoxy)phenoxathiin-10,10-dioxide has been determined and is provided herein. This new solid form of 3-fluoro-7-(2,2,2-trifluoroethoxy)phenoxathiin-10,10-dioxide can be characterized by any of a number of its properties, including, but not limited to, melting point, differential scanning calorimetry, infrared spectroscopic spectrum or portions thereof, solubility, methods and conditions under which this form is prepared, and/or precipitated from solution, and, when in crystalline form, the crystalline form can be characterized according to the diffraction pattern or portions thereof.
