Preparation according to Example 22: 3-(3-chloro-4-fluorophenyl)pyrrolidin-3-ol (0.8 g, 3.72 mmol), potassium carbonate (1.03 g, 7.45 mmol), iodopropane (0.83 mg, 4.86 mmol), acetonitrile (20 mL). Purification by flash chromatography on silica gel (ethyl acetate/methanol, 1:1 to 0:1). Yield: 520 mg. The amine was converted to the fumaric acid salt and recrystallized from ethanol/diethyl ether: M.p. 157.9° C.; MS m/z (relative intensity, 70 eV) 257 (M+, 8), 228 (bp), 198 (30), 157 (15), 84 (88).
