The second method for the preparation of p-aminobenzenesulfone-N1-3, 4-dimethylbenzoylamide is described. 3, 4-Dimethylbenzimido ethyl ether was condensed with p-acetaminobenzenesulforiamide and p-nitrobenzenesulfonamide yielding p-acetaminobenzeneselfone-N1-3, 4-dimethylbenzamidine and p-nitrobenzenesulfone-N1-3, 4-dimethylbenzamidine, respectively. The former, on treatment with 15% hydrochloric acid, yielded p-aminobenzenesulfone-N1-3, 4-dimethylbenzoylamide, while the latter yielded the same compound by the simultaneous reduction and hydrolysis of the N4-acetyl group by treatment with tin and hydrochloric acid.
