Procedure

Preparation according to Example 1: 4-[2-fluoro-3-(trifluoromethyl)phenyl]piperidine (0.45 g, 1.82 mmol), acetonitrile (20 ml), potassium carbonate (0.6 g, 1.1 mmol) and 1-bromo-2-methoxyethane (0.16 ml, 2.0 mmol). Yield: 0.34 g (61%). The amine was converted to the hydrochloric acid salt and recrystallized from ethanol/diethyl ether: M.p. 180-181° C. MS m/z (relative intensity, 70 eV) 305 (M+, 2), 261 (14), 260 (bp), 217 (5), 177 (9).
