Procedure

27.2 g of the thus obtained N-(benzenesulfonyl)-p-nitrobenzamide, 270 g of water, and 5.4 g of glacial acetic acid were charged in a 1,000-ml reaction flask, 54 g of iron powder was slowly added, and a reductive reaction was carried out for 12 hours. The reaction solution was made alkaline with sodium carbonate and filtered. The transparent filtrate was acidified with acetic acid to obtain 19.8 g of N-(benzenesulfonyl)-p-aminobenzamide.
