Abstract
Process for the production of N- (2,3-dimethylphenyl) anthranilic acid and its salts, characterized in that a sulfonic acid compound of formula ** (See formula) ** or a salt or ester thereof, is heated with aqueous mineral acid, and, if desired, the N- (2,3-dimethylphenyl) anthranilic acid thus obtained is converted, by alkalization, into a salt; where R is a carboxy group to a hydrolysable group to pass to carboxy group, with an aqueous acid, R1 is hydrogen or a group removable by acid hydrolysis and m and n are 0 or 1, at least one of said m and n being 1.
