Abstract

A process for the preparation of sulfamylanthranilic acids of the general formula ** (See formula) ** wherein R represents the benzyl, furfuryl or tenyl group, characterized in that 3-sulfamyl-4-chloro-6-halogeno-benzoic acid halides, 3-sulfamyl-4-chloro-6-halogen acid amides, are reacted -benzoic acid or 3-sulfamyl-4-chloro-6-halogeno-benzoic acid hydrazides with amines of the general formula NH2R and the correspondingly substituted 4-chloro-5-sulfamylanthranilic acid amides obtained are saponified by alkaline route, optionally without isolate them (Machine-translation by Google Translate, not legally binding)
