Reaction Steps

To 52.1 g of N-(5-nitro-2-phenoxyphenyl)methanesulfonamide was added 51 ml of an aqueous solution containing 2.7 g of ammonium chloride, and then 42.5 g of an iron powder was added thereto with heating at 80° C. with stirring, followed by stirring for 2 hours. To the reaction cooled to 50° C. were added ethyl acetate and water. The insoluble substances were removed by filtration, and the filtrate was extracted with ethyl acetate. The organic layer was successively washed with water and a saturated aqueous sodium chloride solution, and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was recrystallized from ethanol to give 29.6 g of N-(5-amino-2-phenoxyphenyl)methanesulfonamide.
