EFFICIENT SCALABLE APPROACH FOR CLOPIDOGREL BISULFATE THROUGH PREFERENTIAL CRYSTALLIZATION OF()-2-(2-CHLOROPHENYL)-(6,7-DIHYDRO-4HTHIENO[3,2,C]PYRIDINE-5-YL-ACETAMIDE.

Abstract


The present work deals with the efficient synthesis of Clopidogrel Bisulfate (Generic name : Plavix by Sanofi) through resolution of an important precursor () -2-(2-chlorophenyl)-(6,7-dihydro-4Hthieno[3,2,c]pyridine-5-yl-acetamide by preferential crystallization. This compound was synthesized in its racemic form as per the known process and was resolved by preferential crystallization. These efforts led to a successful isolation of enantiomerically pure isomers of ()-2-(2-chlorophenyl)-(6,7-dihydro-4H-thieno[3,2,c]pyridine-5-ylacetamide.
