Abstract

The present invention provides a reproducible, novel, commercially feasible process to obtain Olanzapine Form-I of substantial polymorphic purity with minimal number of steps using minimal number of solvents by condensation of 4-Aminomethyl-10H-thieno [2, 3-b] [1, 5] benzodiazepine hydrochloride with N-methyl piperazine followed by isolation of Olanzapine methylene chloride solvate and conversion of the same to Olanzapine Form-I.
