Reaction Steps

To a mixture of phenylacetic acid (327 mg, 2.40 mmol, 1.2 equiv.) and 1-(tert-butoxycarbonyl)-4-(2-hydroxyethyl)piperidine (459 mg, 2.00 mmol) in CH2Cl2 (10 mL) were added DCC (495 mg, 2.40 mmol, 1.2 equiv.) and DMAP (12.2 mg, 100 μmol, 0.1 equiv.). The reaction mixture was allowed to stand overnight. After filtration, the liquid phase was washed with brine and dried over Na2SO4. After the solvent was removed, the residue was purified by CC (SiO2, hexane/EtOAc 4:1). The ester (672 mg, 97%) was obtained as a colorless oil. 1H NMR (CDCl3, 400 MHz) δ 7.31 (m, 5H), 4.14 (t, 2H, J=6.8 Hz), 4.03 (d, 2H, J=13.2 Hz), 3.61 (s, 2H), 2.60 (dt, 2H, J=2.0, 12.8 Hz), 1.56 (m, 5H), 1.45 (s, 9H), 1.06 (m, 2H).
