Reaction Steps

Four milliliters of ethanol and 4 ml of tetrahydrofuran were added to 0.605 g of N-(n-pentanesulfonyl)-3-(N-methy-2,4-dichlorobenzylamino)-4-nitrobenzamide, and subsequently 10 ml of an aqueous solution containing 3.10 g of sodium hydrosulfite was added thereto. The mixture was stirred at 80° C. for 20 minutes and then extracted with water and ethyl acetate. The organic layer was washed with water and concentrated. The resulting residue was crystallized from ether, filtrated, and dried to obtain 0.126 g of 4-amino-3-(N-methyl-2,4-dichlorobenzylamino)-(N-(n-pentanesulfonyl))benzamide (32).
