실험 절차

Preparation according to Example 1: 1-[2-fluoro-3-(trifluoro-methyl)phenyl]piperazine (0.97 g, 3.9 mmol), acetonitrile (50 ml), potassium carbonate (0.81 g, 5.86 mmol) and 1-iodopropane (0.457 ml, 4.6 mmol). Yield: 0.57 g (50%). 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) 290 (M+, 22), 262 (13), 261 (bp), 218 (18), 190 (22).
