Abstract

Procedure for the construction of 10-oxo-10,11-dihydro-5h-dibenz (b, f) azepin-5-carboxamide. It consists in hydrolyzing 10-chlorine-5h-dibenz (b, f) azepin-5-carboxamide. Hydrology is used sulfuric acid, whose concentration varia between 90 and 96 per 100, and is performed at a temperature comprised between 10 and 30 c.
