실험 절차
A suspension of 1-ethyl-4-(2-fluoro-4-nitro-phenyl)-piperazine (1.24 g, 15.1 mmol) and Raney Nickel (13 mg) in MeOH (6 mL) is stirred for 17 h at RT, under a hydrogen atmosphere. The reaction mixture is filtered through a pad of celite and concentrated to afford the title compound as a purple oil: ESI-MS: 224.1 [MH]+; tR=0.90 min (system 1).
