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:
A process is provided for selectively preparing novel stable crystalline forms, namely selectively and consistently preparing Form N-1 of the free acid peliglitazar, Form N-2 of the free acid peliglitazar and Form P-1 of the L-lysine salt of the free acid peliglitazar. The process preferably employs solvent systems which produce crystals having suitable flow properties and desired particle size.Novel Form N-1 crystals of the free acid, Form N-2 crystals of the free acid, Form P-1 crystals of the L-lysine salt of the free acid, pharmaceutical compositions containing such novel forms and a method of treating diabetes, dyslipidemia and atherosclerosis employing such novel forms are also provided.
