実験手順
To a solution of cyclohexylamine (1.50 g, 15.1 mmol) in tetrahydrofuran (15 mL) was added 2,4-butane sultone (2.04 g, 14.4 mmol). The solution stirred at reflux for 2 hours. The reaction was cooled to room temperature. The solid was collected by filtration and dried in vacuo. Yield: 59%. 1H NMR (DMSO, 500 MHz) δ ppm 8.50 (s (broad), 1H), 3.02 (m, 2H), 2.93 (m, 1H), 2.60 (m, 1H), 1.93 (m, 3H), 1.75 (m, 3H), 1.57 (m, 1H), 1.21 (m, 4H), 1.11 (m, 4H). 13C (DMSO, 125 MHz) δ ppm 56.23, 53.20, 43.09, 29.54, 29.41, 29.39, 25.40, 24.42, 17.23. ES-MS 234 (M−1).
