실험 절차

tert-Butylamine (3.0 mol, 315.3 mL) was dissolved in THF (2.5 L). The solution was cooled to −20° C. and treated slowly with 3-chloropropanesulfonyl chloride (1.5 mol, 182.4 mL). The reaction mixture was warmed to room temperature and stirred for 24 hours. The mixture was filtered, and the filtrate was concentrated in vacuo. The concentrate was dissolved in dichloromethane (2.0 L), washed with 1N HCl (1.0 L), water (1.0 L), brine (1.0 L), dried over Na2SO4, filtered, and concentrated in vacuo to give a slightly yellow solid, which was crystallized from hexane to provide the desired product as a white solid (316.0 g, 99%). 1H NMR (CDCl3) δ 1.38 (s, 9H), 2.30-2.27 (m, 2H), 3.22 (t, J=7.35 Hz, 2H), 3.68 (t, J=6.2 Hz, 2H), 4.35 (br, 1H).
