Procedure
1-Benzyl-3-pyrrolidinol (1.1 g) in toluene (10 mL) at 0° C. was treated with triethylamine (1 mL) and methanesulfonyl chloride (0.53 mL), warmed to room temperature, washed with saturated aqueous sodium bicarbonate, water, and brine, dried over anhydrous sodium sulfate, and concentrated. 1H NMR (300 MHz, DMSO-d6) δ 7.31 (s, 5H), 5.21 (m, 1H), 3.65 (q, 2H), 2.82 (m, 2H), 2.5 (m, 2H), 2.36 (m, 2H), 2.1 (m, 1H).
