실험 절차
(3S,4S)-1-Benzyl-4-(4-chloro-phenyl)-pyrrolidine-3-carboxylic acid methyl ester (7.0 g, 21.0 mmol) were dissolved in methanol (60 mL) and treated with NaOMe (30% in methanol, 0.9 mL, 4.50 mmol) for 24 h at ambient temperature. The volatiles were removed and the residue was subjected to column chromatography (silica gel, heptane/ethyl acetate 9:1) to yield the title compound (5.9 g, 84%) as a colorless oil. ES-MS m/e: 330.8 (M+H+).
