Procedure
A 1.01 g portion of benzyl 3-methylpiperazine-1-carboxylate synthesized in Reference Example 10, 814 mg of 4-fluoro-2-trifluoromethylbenzonitrile and 2.38 g of potassium carbonate were added to 20 ml of DMF and stirred at 100° C. for 20 hours. This was mixed with water, extracted with ethyl acetate and dried, and then the solvent was evaporated. The resulting residue was purified by a silica gel column chromatography to obtain 440 mg of the title compound from ethyl acetate-hexane (3:1, v/v) eluate.
