실험 절차
To a solution of 3,5-diphenyl-1H-pyrazole (0.36 g, 1.65 mmol) in N,N-dimethylformamide (8.6 mL) was added sodium hydride (60% in oil, 66 mg, 1.65 mmol) under stirring at room temperature, and the mixture was stirred at the same temperature for 30 min. To the reaction mixture was added sodium iodide (22 mg, 0.15 mmol) and a solution of methyl 4-(bromomethyl)-3-isopropoxybenzoate (0.43 g, 1.50 mmol) in N,N-dimethylformamide (4.3 mL), and the mixture was stirred at room temperature for 3 hr. The reaction mixture was diluted with ethyl acetate, washed with water and saturated brine, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1-hexane/ethyl acetate=4/1) to give the title compound (0.59 g, yield 92%) as a colorless oil.
