실험 절차

1 g of 2-(4-nitrophenylamino)ethanesulfonamide (12) was suspended in 10 mL of ethanol. At room temperature, the suspension was poured onto a reductive solution of sodium hydrosulfite (8 g)—1N sodium hydroxide (30 mL). After decolorization, a precipitate formed. 0.7 g of crude product was isolated by suction-filtering and reslurrying in water.
