Reaction Conditions

Reaction Steps

2,4-butanesultone (1.27 g, 8.9 mmol) was added to an ice-chilled solution of dimethylamine (40% w/w in water). The solution was stirred at 0° C. for 4 hours. The solvent was evaporated in vacuo until complete dryness. The solid was washed with acetone (50 mL), collected by filtration and dried in vacuo. 1H NMR (D2O, 500 MHz) δ ppm 3.18 (t, 2H, J=8.1 Hz), 2.85 (m, 1H), 2.76 (s, 6H), 2.09 (m, 1H), 1.81 (m, 1H), 1.17 (d, 3H, J=7.3 Hz). 13C (D2O, 125 MHz) δ ppm 55.65, 53.05, 42.88, 26.72, 14.81. ES-MS182a (M+1).
