Reaction Steps

In a sealed tube a mixture of 3-(3,4-difluorophenyl)pyrrolidin-3-ol (0.192 g, 0.963 mmol), acetonitrile (3 mL), potassium carbonate (0.133 g, 0.963 mmol) and isopropylbromide (0.118 g, 0.963 mmol) was heated under microwave irradiation at 120° C. for 25 minutes. The mixture was filtrated and evaporated. Purification by flash chromatography on silica gel (ethyl acetate/methanol, 4:1 to 1:1) and by HPLC on Waters OBD C18, 5 μm (MeOH/33 mM NH3, 20:80 to 55:45) gave the title compound (0.092 g). The amine was converted to the fumaric acid salt and recrystallized from ethanol/diethyl ether/diisopropyl ether: M.p. 143-147° C.; MS m/z (relative intensity, 70 eV) 241 (M+, 11), 226 (bp), 182 (46), 85 (53), 84 (31).
