Abstract

NEW MATERIAL:A heterocyclic benzamide compound of formula I: (R1 and R2 are lower alkyl groups; Y is H, SO2NH2, SO3H, SO3-aryl, or SO2NH-acyl group).
EXAMPLE: N-Ethyl-2-(2-methoxy-5-sulfamoylbenzamidomethyl)pyrrole.
USE: Central nervous system depressants.
PROCESS: A compound of formula II or its reactive derivative at the carboxyl group, e.g. an acid halide, anhydride, or alkoxycarbonyl derivative, is reacted with a compound of formula III to give the objective compound of formula I. When the carboxyl group of the compound of formula II is free, a condensing agent, e.g. cyclohexylcarbodiimide or phosphorus pentachloride, is preferably used. A petroleum, aromatic, or chlorinated hydrocarbon may be used as a solvent.
