Participants

Reaction Steps

To a solution of N-(3-chlorobenzyl)-4-nitro-3-(piperazin-1-yl)benzenamine (77 mg, 0.17 mmol) in dry dichloromethane (1.0 mL) was added a saturated solution of HCl in diethyl ether (15 mL). The reaction mixture was stirred for 4 hours. The solvent was evaporated and the precipitate was recrystallized from methanol (0.3 mL), dichloromethane (0.5 mL) and diethyl ether (5 mL). The product was collected by filtration and dried in vacuo to afford the title compound (54 mg, 82% yield after recrystallization). 1H NMR (400 MHz, CD3OD): δ 8.01 (d, 1H), 7.37-7.27 (m, 4H), 6.39 (d, 1H), 6.25 (s, 1H), 4.45 (s, 2H), 3.36 (m, 4H), 3.23 (m, 4H); MS (ESI) m/z: Calculated for C17H20ClN4O2: 347.13; Observed: 347.4 (M++1) [corresponding to the free base].
