  • Patent number: 9169265
    Abstract: The object of the present invention is a process for preparing the 2-acetoxi-5-(2-fluor-?-cyclopropyl-carbonyl-benzyl)-4,5,6,7-tetrahydro-4H-thieno[3,2-c]pyridine (prasugrel) of the formula (I). The process starts from crystalline 5-trityl-4,5,6,7-tetrahydro-thieno[3,2-c]pyridine of the formula (VI). Further objects of the present invention are two novel crystalline forms of 5-trityl-4,5,6,7-tetrahydro-thieno[3,2-c]pyridine of the formula (VI) and the use thereof for preparing the compound of the formula (V) and process preparing thereof.

  • Patent number: 8877799
    Abstract: The present invention relates to the use of novel vildagliptin complexes for the manufacture of high purity vildagliptin of Formula I and/or pharmaceutical acceptable salts thereof. Further objects of the present invention are pharmaceutically acceptable complexes of vildagliptin and/or amorphous and crystalline forms, anhydrous forms, amorphous and crystalline hydrates, amorphous and crystalline solvates of the complexes and a process for the preparation thereof. Another object of the present invention is the high purity vildagliptin and pharmaceutically acceptable salts thereof prepared form the vildagliptin complexes of the present invention, a process for the preparation thereof and pharmaceutical compositions containing vildagliptin base, pharmaceutically acceptable salts and/or complexes and use thereof for the treatment of type 2 diabetes (NIDDM). The present invention provides pharmaceutically advantageous high purity vildagliptin complexes.

  • Patent number: 8507513
    Abstract: The present invention relates to a new process for the preparation of rosuvastatin [7-[4-(4-Fluorophenyl)-6-isopropyl-2-(methanesulphonyl-methyl-amino)-pyrimidin-5-yl]-(3R,51S)-dihydroxy-hept-6-enoic acid] of the formula (I) salts formed with bivalent cations, preferably with calcium or zinc ions, characterized in that rosuvastatin tert.-butylammonium salt is reacted with the appropriate bivalent cation, preferably with calcium or zinc ions in a mixture of a water immiscible or slightly miscible organic solvent and water and the formed salt is isolated.

  • Publication number: 20130030183
    Abstract: The object of the present invention is a one-pot process for preparing the 2-acetoxy-5-(2-fluoro-?-cyclopropyl-carbonyl-benzyl)-4,5,6,7-tetrahydro-4H-tieno[3,2-c]-pyridine (prasugrel) of the formula (I) by reacting the 5,6,7,7a-tetrahydro-4H-tieno[3,2-c]-pyridine-2-on of the formula (II) with 2-bromo-1-cyclopropyl-2-(2-fluorophenyl)-etanone of the formula (III) or with 2-chloro-1-cyclopropyl-2-(2-fluorphenyl)-etanone of the formula (IIIa) and acetylating of the formed compound of the formula (IV), wherein the reaction is carried out in the presence of an organic base with an acetylation agent without isolating the compound of the formula (IV). The coupling and acetylation are carried out in the presence of the same organic base such as triethylamine, N,N-diisopropyl-ethylamine or pyridine. At the end of the process the prasugrel of the formula (I) is purified by recrystallization from an organic solvent or a mixture of solvents.
