Abstract

Process for the production of N- (2,3-dimethylphenyl) anthranilic acid and its salts, characterized in that a salt is reacted by the addition of an acid N- (2,3-dimethylphenyl) anthranilic substituted amino acid of the formula ** (See formula) ** with nitrous acid under acidic conditions, and the intermediate diazonium compound thus produced is reacted without isolation or purification, with hypophosphorous acid under acidic aqueous conditions and, if desired, converted into a salt by basification of N- (2, 3-dimethylphenyl) anthranilic acid thus produced where X represents hydrogen or an amino group at positions 4, 5 or 6 with respect to the carboxyl group and Y represents hydrogen or an amino group at positions 4 or 5 with respect to the group -NH-.
