Title:
METHOD FOR PRODUCING DIBENZOTHIAZEPINE DERIVATIVE
Document Type and Number:
Japanese Patent JP2011126887
Kind Code:
A
Abstract:

To provide a new method for producing a dibenzothiazepine derivative useful as a starting material for producing 11-[4-(2-(2-hydroxyethoxy)ethyl)]-1-piperazinylbenzothiazepine derivative useful as an antipsychotic agent.

This compound expressed by formula (5) [wherein, each of symbols is specifically defined] is produced by reacting a specific nitrobenzene derivative with a specific thiosalicylic acid derivative, thereafter reducing the obtained 2-nitro-2'-carboxy-diphenyl sulfide derivative, and further performing the dehydrating condensation of the obtained 2-amino-2'-carboxy-diphenyl sulfide derivative.
