実験手順
7.5 G. of 4-acetylamino-3-nitrobenzenesulfonamide is dissolved in 60 ml. of 6N hydrochloric acid and refluxed for 2 hours. The reaction mixture is cooled, filtered, and the solid material washed with water and dried. The dried 4-amino-3-nitrobenzenesulfonamide has a m.p. of 208°-210° C. and is of sufficient purity for use in the next step.
