A mixture of 5-(2-phenylethyl)-3-[4-(trifluoromethyl)phenyl]-1H-pyrazole (318 mg, 1.01 mmol), [4-(chloromethyl)phenyl]methanol (240 mg, 1.53 mmol), potassium carbonate (276 mg, 2.0 mmol) and N,N-dimethylformamide (10 mL) was stirred at 120° C. for 1 hr. The reaction mixture was poured into 1 N hydrochloric acid, and the mixture was extracted with ethyl acetate. The ethyl acetate layer was dried using a Presep Dehydration tube (manufactured by Wako Pure Chemical Industries, Ltd.) and concentrated. The residue was purified by silica gel column chromatography (10%-80% ethyl acetate/hexane) to give the title compound (220 mg, yield 50%) as a yellow oil.
