실험 절차

To a stirred solution of enantiomer 2 of 3-(3,4-difluorophenyl)-1-ethyl-3-methoxypyrrolidine (0.011 g, 0.045 mmol) in dichloromethane (2 ml) was added 3-chloroperoxybenzoic acid (77%) (0.0204 g, 0.09 mmol). The mixture was stirred at room temperature for 30 min and was then filtrated through a plug of aluminiumoxid (basic) which was eluted with dichloromethane:MeOH (9:1). The crude product was analyzed by LCMS (Qtrap, Applied Biosystems, Q1 MS). analysis showed <95% conversion: MS (m+1)/z; 258 (M+1, bp), 259 (23), 257 (3), 214 (7), 142 (5).
