实验过程

To a solution of [4-(4-Benzyl-piperazin-1-yl)phenyl]-methanol in EtOH (50 ml) under a blanket of argon was added a suspension of 10% palladium on charcoal (1.5 g) in EtOH (150 ml). Hydrogen was bubbled through the suspension for 1 h and then the reaction mixture was stirred under a blanket of hydrogen for 60 h at RT. The catalyst was filtered off and the solvent removed in vacuo to yield the title compound as a white solid (4.8 g, 100%). 1H-NMR δ (CDCl3) 7.30–7.21 (2H, m, ArH), 6.94–6.88 (2H, m, ArH), 4.59 (2H, s), 3.18–2.98 (8H, m). HPLC: 0.5 min (37%@214 nm), 0.7 min (55%@214 nm), multiple peaks due to salt formation from TFA buffer; LRMS +ve: 193 (M+1, 70).
