Acetonitrile → 4-(Adamantyl)amino-2-butanesulfonic acid

Participants

Reaction Steps

To a solution of 2-adamantanamine (1.99 g, 13.1 mmol) in acetonitrile (15 mL) was added 2,4-butane sultone (1.87 g, 13.8 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 acetonitrile (3×25 mL) and dried in vacuo. 1H NMR (DMSO, 500 MHz) δ ppm 8.53 (s (broad), 1H), 3.33 (m, 2H), 2.61 (m, 1H), 2.10 (s, 3H), 1.93 (m, 1H), 1.77 (m, 7H), 1.61 (m, 6H), 1.12 (d, 1H, J=6.8 Hz). 13C (DMSO, 125 MHz) δ ppm 56.20, 53.34, 35.85, 29.75, 29.04, 17.206. ES-MS 288 (M+1).
