実験手順: A mixture of 3-(phenylamino)propan-1-ol (Huang, et al., J.Org.Chem.; 58(23):6235-6246(1993)) (65.6 g, 0.43 mol), ethyl 4-bromobutyrate (104.5 g, 0.54 mol) and 100 mL of ethyldiisopropylamine is stirred at 100° C. for 1 h. The reaction is cooled to room temperature and partitioned between water 400 mL and ethyl acetate (500 mL). The organic layer is washed with saturated NaHCO3, brine and dried over Na2SO4. The oil obtained after concentration is chromatographed on silica eluting with 10% EtOH/CHCl3. Concentration of the appropriate fractions affords 115 g (100%) of the desired product as a colorless, viscous oil. 1H NMR (CDCl3) δ 7.23 (m, 2H), 6.72 (m, 3H), 4.14 (q, J=7 Hz, 2H), 3.72 (t, J=6 Hz, 2H), 3.43 (t, 7 Hz, 2H), 3.34 (t, 7 Hz, 2H), 2.35 (t, 7 Hz), 1.88 (m, 4H), 1.26 (t, 7 Hz, 3H).
