반응 단계

To a solution of D-Phenylalaninamide (1.83 g, 11.1 mmol) in acetonitrile (20 mL) was added 1,3-propane sultone (1.29 g, 10.6 mmol). The solution was stirred at reflux for 2.5 hours. The reaction mixture was cooled to room temperature. The solid was filtered and washed with acetonitrile (2×20 mL). The solid product was suspended in EtOH (75 mL). The suspension was stirred at reflux for 1 hours. The solid material was filtered, washed with acetone (1×25 mL) and dried in vacuo, affording the title compound (2.62 g, 89%). 1H NMR (D2O, 500 MHz) δ ppm 7.28 (m, 3H), 7.19 (m, 2H), 4.05 (m, 1H), 3.19 (dd, 1H, J=5.3 Hz, 14.2 Hz), 3.04 (m, 3H), 2.86 (t, 2H, J=5.8 Hz), 2.03 (m, 2H). 13C (D2O, 125 MHz) δ ppm 170.39, 133.73, 129.62, 129.26, 128.15, 61.57, 47.99, 45.57, 36.21, 21.45. [α]D=−20.7° (c=0.0038 in water), ES-MS 285 (M−1).
