실험 절차

30.6g (0.6 mole) of 4-(N-p-toluenesulfonyl)amino-3-methyl-nitrobenzene 1g of fresh-developed Raney nickel and 60ml of tetrahydrofuran were charged into an autoclave and the autoclave was pressurized to 60kg/cm2 with hydrogen. The reaction was carried out at 50° to 100° C while stirring. After completion of the reaction, the Raney nickel was removed from the reaction solution and the tetrahydrofuran was distilled out to obtain brown 4-(N-p-toluenesulfonyl)amino-3-methylaniline. The product was recrystallized from ethyl acetate to obtain 24g of yellow-brown crystals.
