実験手順

To a solution of (−)-3-(3,4-difluorophenyl)-3-methoxypyrrolidine (0.013 g, 0.061 mmol) and triethylamine (17.1 μL, 0.122 mmol) in tetrahydrofuran (2 ml), was added iodoethane (7.3 μL, 0.091 mmol), the resulting solution was stirred at ambient temperature for 24 h. The crude mixture was purified on a Biotage Isolute SCX-3 SPE column (washed with methanol and eluted with methanol/triethylamine, 4:1). The solvent was evaporated and the crude product was analyzed by GCMS. Analysis showed 76% conversion. MS m/z (relative intensity, 70 eV) 241 (M+, 7), 226 (57), 211 (24), 141 (43), 71 (bp).
