실험 절차

To a solution of octylamine (2.00 g, 15.5 mmol) in 2-butanone (17 mL) was added 2,4-butane sultone (2.21 g, 16.2 mmol). The solution was stirred at reflux for 2 hours. The reaction was cooled to room temperature. The solid was collected by filtration, washed with acetone (2×25 mL) and dried in vacuo. It was suspended in a solution of 25% EtOH/acetone (50 mL). The suspension was stirred for 5 minutes. The solid was collected by filtration, washed with acetone (2×25 mL) and dried in vacuo. 1H NMR (DMSO, 500 MHz) δ ppm 8.45 (s (broad), 1H), 3.01 (m, 1H), 2.84 (m, 2H), 2.58 (m, 1H), 1.92 (m, 1H), 1.75 (m, 1H), 1.51 (m, 2H), 1.10 (d, 1H, J=6.8 Hz), 0.85 (t, 3H, J=6.8 Hz). 13C (DMSO, 125 MHz) δ ppm 53.05, 47.27, 46.15, 31.83, 29.42, 29.13, 26.51, 26.27, 22.75, 17.19, 14.64. ES-MS 266 (M+1).
