実験手順
A suspension of 1-ethyl-4-(4-nitro-phenyl)-piperidine (0.8 g, 4.92 mmol) and 10% palladium on carbon (0.1 g) in EtOH (10 mL) is stirred for 3 h at RT, under a hydrogen atmosphere. The reaction mixture is filtered through a pad of celite and concentrated. The residue is purified by silica gel column chromatography (DCM/MeOH+1% NH3aq, 95:5) to provide the title compound. ESI-MS: 205.1 [MH]+; TLC: Rf=0.29 (DCM/MeOH+1% NH3aq, 95:5).
