PROCESS FOR HIGH YIELD PRODUCTION OF CLOPIDOGREL BY RACEMIZATION OF RESIDUAL LIQUID

The present invention relates to a process for preparing S-(+)-clopidogrel in high yield by means of racemization of filtrate, and particularly to a process comprising (a) conducting an optical resolution by converting racemic carboxylic acid of clopidogrel to diastereomer salt using (+)-cinchonine, (b) preparing carboxylic acid of S-(+)-clopidogrel by extraction using an appropriate solvent under an acidic condition, (c) preparing optically pure S-(+)-clopidogrel by reacting the carboxylic acid of S-(+)-clopidogrel with methanol, wherein a filtrate, which remains after collecting the diastereomer salt as solid precipitates, is recycled after being converted to a racemic carboxylic acid of clopidogrel via racemization under a basic condition, thereby maximizing the yield of S-(+)-clopidogrel.
