참여 물질

반응 단계

To a solution of 1-methyl-4-(4-nitrobenzyl)piperazine (4.0 g) in methanol (100 mL) at room temperature under nitrogen atmosphere was added Raney nickel (1.6 gm). The reaction mixture was stirred for 2 hr under hydrogen atmosphere. The progress of the reaction was monitored by TLC and upon completion of the reaction, the mixture was filtered under nitrogen atmosphere and the solvent was removed under reduced pressure to give 4-[(4-methylpiperazin-1-yl)methyl]aniline (3.2 g). 1H NMR (CDCl3, 200 MHz) δ: 7.13 (2H, d, J=8.4 Hz), 6.61 (2H, d, J=8.4 Hz), 3.41 (2H, s), 2.45 (8H, bm), 2.27 (3H, s); m/e=206 (M+1).
