The invention discloses an improved process for racemization of methyl (R)(-) alpha-(2-chlorophenyl)-6,7-dihydro-thieno[3,2-c]pyridine-5(4H)-acetate , a stereoisomer formed in the synthesis of clopidogrel i.e. methyl (S)-(+)-alpha (2-chlorophenyl)-6,7-dihydro-thieno[3,2-c]pyridine-5(4H)-acetate or its salts. The invention is also for an improved process for production of clopidogrel or its pharmaceutically acceptable salts. The invention further discloses novel clopidogrel salts and pharmaceutical compositions comprising them.
