Reaction Steps
Preparation according to Example 1: 1-[2-fluoro-3-(trifluoro-methyl)phenyl]piperazine (0.5 g, 2.0 mmol), acetonitrile (25 ml), potassium carbonate (0.42 g, 3.0 mmol) and 1-bromo-2-methoxyethane (0.189 ml, 2.0 mmol). Yield: 0.26 g (42%). The amine was converted to the hydrochloric acid salt and recrystallized from ethanol/diethyl ether: M.p. 170-171° C. MS m/z (relative intensity, 70 eV) 306 (M+, 9), 262 (13), 261 (bp), 218 (23), 190 (23).
