実験手順
To a stirred solution of (RS)-2-(3-fluoro-phenyl)-pyrrolidine (0.24 g, 1.45 mmol) and triethylamine (0.40 ml, 2.87 mmol) in dichloromethane (40 ml) was added at 0° C. toluene-4-sulfonyl chloride (0.42 g, 2.20 mmol). The mixture was stirred at RT for 16 h, evaporated, dissolved in water (40 ml) and extracted with ethyl acetate (2×40 ml). The combined organic layers were washed with water (40 ml), brine (40 ml), dried (MgSO4) and evaporated. The crude product was purified by crystallization from ethyl acetate/hexane to give the product (0.38 g, 83%) as a white solid, m.p. 116° C. and MS: m/e=319 (M+).
