    摘要: A process is provided for preparing the HIV protease inhibitor atazanavir bisulfate wherein a solution of atazanavir free base is reacted with concentrated sulfuric acid in an amount to react with less than about 15% by weight of the free base, seeds of Form A crystals of atazanavir bisulfate are added to the reaction mixture, and as crystals of the bisulfate form, additional concentrated sulfuric acid is added in multiple stages at increasing rates according to a cubic equation, to effect formation of Form A crystals of atazanavir bisulfate.A process is also provided for preparing atazanavir bisulfate as Pattern C material. A novel form of atazanavir bisulfate is also provided which is Form E3 which is a highly crystalline triethanolate solvate of the bisulfate salt from ethanol.

    摘要: Processes are provided for selectively preparing novel stable crystalline salt forms, selectively and consistently, namely, preparing Form N-1 of the methanesulfonic acid salt, and Form N-1 and Form N-4 of the hydrochloric acid salt of the p38 kinase inhibitor 4-[[5-[(cyclopropylamino)carbonyl]-2-methylphenyl]amino]-5-methyl-N-propylpyrrolo[2,1-f][1,2,4]triazine-6-carboxamide. The processes preferably employ solvent systems including formic acid/acetone and formic acid/methylethyl ketone which produce crystals having suitable flow properties and desired particle size, and solvents such as N,N-dimethylformamide and N,N-dimethylacetamide may be employed as well.Novel Form N-1 crystals of the Form N-1 and Form N-4 crystals of the hydrochloride salt and Form N-1 crystals of the methanesulfonic acid salt of the above free base, pharmaceutical compositions containing such novel forms and a method of treating p38 kinase associated conditions, including rheumatoid arthritis are also provided.
