실험 절차

To a mixture of 4-phenylpiperidine 41g (5 mmol), EDCI (6 mmol), HOBt (5.5 mmol) and NMM (6 mmol) in CH2Cl2 (50 mL) was added 3,4,5-trimethoxybenzoic acid (5.3 mmol) and stirring continued at RT for overnight. The reaction mixture was diluted with CH2Cl2 (100 mL) and sequentially washed with water, satd. NaHCO3, brine and dried over MgSO4. The solvent was removed under reduced pressure to yield a crude product, which was purified by column chromatography to obtain pure compound 1g. (57.9%). 1H NMR (CDCl3) δ 7.35-7.21 (m, 5H), 6.66 (s, 2H), 4.84 (br, 1H), 3.95 (br, 1H), 3.88 (s, 6H), 3.86 (s, 3H), 3.20-2.87 (br, 2H), 2.85-2.74 (tt, 1H, J=3.6 Hz, J=15.6 Hz) 1.92 (br, 2H), 1.70 (br, 2H); MS (ESI) m/z 378.1 (M+Na)+.
