실험 절차

To a solution of 1,2-dimethylpropylamine (10.0 g, 115 mmol) in tetrahydrofuran (80 mL) was slowly added a solution of 1,3-propane sultone (13.7 g, 110 mmol) in THF (20 mL). The solution was stirred at reflux for 2 hours. The reaction mixture was cooled to room temperature. The solid product was collected by filtration, washed with THF (50 mL) and EtOH (50 mL). The resulting solid was dried in vacuo, to afford compound DQ (17.5 g, 76%). 1H NMR (D2O, 500 MHz) δ ppm 3.07 (m, 3H), 2.88 (t, 2H, J=7.3 Hz), 1.97 (m, 3H), 1.10 (d, 3H, J=6.8 Hz), 0.85 (d, 3H, J=6.8 Hz), 0.81 (d, 3H, J=6.8 Hz). 13C NMR (D2O, 125 MHz) δ ppm 59.79, 48.19, 44.18, 29.72, 21.51, 18.44, 15.02, 10.71. ES-MS 232 (M+Na).
