To a mixture of 3-(3,5-difluorophenyl)pyrrolidin-3-ol (0.50 g, 2.5 mmol) in acetonitrile (25 mL) was added sodium carbonate (0.34 g, 6.25 mmol) and iodoethane (0.39 g, 2.5 mmol) and the mixture was refluxed for 1 h. Water (50 mL) was added and the aqueous phase was extracted with ethyl acetate (2×50 mL), the combined organic phase was dried (MgSO4) and evaporated. Purification by flash chromatography on silica gel (ethyl acetate/methanol, 1:1) gave the title compound (0.12 g). The amine was converted to the fumaric acid salt and lyophilized from water.
