实验过程

To a solution of tert-butylamine (1.0 mL, 9.5 mmol) in tetrahydrofuran (4 mL) was added 1,4-butane sultone (1.36 g, 10.0 mmol) at room temperature. 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 acetone (2×20 mL), and dried in vacuo; affording compound ER 690 mg, (34%); 1H NMR (D2O, 500 MHz) 8 ppm 2.92 (t, 2H, J=7.1 Hz), 2.82 (t, 2H, J=7.1 Hz), 1.68 (m, 4H), 1.22 (s, 9H). 13C NMR (D2O, 125 MHz) 8 ppm 57.07, 50.30, 40.95, 25.28, 24.96, 21.62. ES-MS 210 (M−1).
