Participants

Reaction Steps

Preparation according to Example 1: 1-[2-fluoro-3-(methylsulfonyl)phenyl]piperazine (0.13 g, 0.52 mmol), acetonitrile (4 ml), potassium carbonate (014 g, 1.1 mmol) and 1-iodopropane (0.05 ml, 0.55 mmol). Yield: 0.1 g (64%). The amine was converted to the hydrochloric acid salt and recrystallized from ethanol/diethyl ether: M.p. 241-243° C. MS m/z (relative intensity, 70 eV) 300 (M+, 18), 272 (14), 271 (bp), 228 (11), 70 (49).
