Novel synthetic methodology for the synthesis of dibenzo azepines

Abstract

New synthetic methodology for the synthesis of dibenzo[b,e][1,4]diazepines, a key intermediates in the manufacturing of Clozapine which is indicated for use in therapy as dopamine receptor antagonist, Antipsychotic drug [1]. Synthesis of 2-(4-chloro-2-nitrophenylamino) benzoic acid methyl ester by simple rearrangement of2-[[2- (4-chloro-2-nitrophenoxy)acetyl]amino]benzoic acid methyl ester. The present work describes a novel, cost-effective and easily scalable process of dibenzo[b,e][1,4]diazepines.
