反応手順

N-1-butanesulfonyl-3-(2,4-dichlorobenzylamino)-4-nitrobenzamide (0.505 g) was added to a mixture of 1.32 g of sodium hydrosulfite, 1 ml of ethanol, 1 ml of tetrahydrofuran and 1 ml of water at room temperature. The mixture was heat-refluxed for 40 minutes. The solvent was distilled off under reduced pressure, and water was added to the residue. The solid material precipitated was collected, and was dried. Further, the resulting material was washed with a mixed solution of 10 ml of methanol and 3 ml of water, and was dried to give 0.220 g of N-1-butanesulfonyl-4-amino-3-(2,4-dichlorobenzylamino)benzamide.
