Abstract

1418762 N - (Aminobenzoyl) - aminoaryl sulphonic acids HOECHST AG 19 Jan 1973 [22 Jan 1972] 2887/73 Heading C2C The invention comprises N-(3- or 4-aminobenzoyl)aminoaryl sulphonic acids of the formula and the alkali metal salts thereof, wherein X is H, halogen, alkyl, alkoxy, CH 3 OCO, C 2 H 5 OCO, mono- or di-alkylamine, CF 3 , C 6 H 5 -, C 6 H 5 O-, -NO 2 or -CN, Y is H, halogen, alkyl or alkoxy, A is a benzene or naphthalene ring (in which former case the SO 3 H group is p with respect to the benzoylamino group) and n is 1 or 2. They may be obtained by reducing the corresponding N-(3- or 4-nitrobenzoyl)aminoaryl sulphonic acids. Examples are given for the production of the compounds which may be isolated as the dicyclohexylamine salts. The N-(3- or 4-nitrobenzoyl)aminoaryl sulphonic acids are obtained by condensing nitrobenzoyl chlorides of the formula with sulphonic acids of the formula or by reacting the corresponding nitrobenzoic acid with an aminoaryl sulphonic acid of the above formula in the presence of PCl 3 in pyridine or quinoline.
