실험 절차
A suspension of 1-ethyl-4-(4-nitro-phenyl)-piperazine (Step 1.10) (6.2 g, 26.35 mmol) and Raney nickel (2 g) in MeOH (120 mL) was stirred for 7 h at rt, under a hydrogen atmosphere. The reaction mixture was filtered through a pad of celite and concentrated to afford 5.3 g of the title compound as a violet solid: ESI-MS: 206.1 [M+H]+; TLC: Rf=0.15 (DCM/MeOH+1% NH3aq, 9:1).
