实验步骤: To a solution of 4-piperidinemethanol (2.28 g, 19.78 mmol) and 4-methoxybenzaldehyde (2.30 mL, 19.77 mmol) in THF/DCE (1:1 by volume, 100 mL) was added acetic acid (1 mL), followed by NaBH(OAc)3 (16.76 g, 79.08 mmol) in small portions. The reaction mixture was stirred at room temperature overnight under N2. The reaction was diluted with DCM and basified to pH=10 with 2 N NaOH solution. The organic layer was separated, dried over Na2SO4, filtered and evaporated under reduced pressure. The residue was purified by chromatography on silica gel (Eluent: 60% EtOAc in hexanes) to give the title compound as a pale yellow oil (2.13 g, 46%). 1H NR (400 MHz, DMSO-d6) δ 1.04-1.13 (m, 2H), 1.28-1.32 (m, 1H), 1.58-1.61 (m, 2H), 1.79-1.86 (m, 2H), 2.75-2.77 (m, 2H), 3.22 (t, J=8.0 Hz, 2H), 3.34 (s, 2H), 3.72 (s, 3H), 4.38 (t, J=4.0 Hz, 1H), 6.85 (d, J=8.0 Hz, 2H), 7.16 (d, J=8.0 Hz, 2H). MS 236 (MH+). The organic layer was separated dried over Na2SO4 filtered evaporated under reduced pressure The residue was purified by chromatography on silica gel (Eluent: 60% EtOAc in hexanes)
