実験手順

N,N-dimethylformamide (11 mL) was added to 2-(4-bromo-2-chlorophenyl)-4-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazole (220 mg), methyl 1-({[4-methyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl]oxy}-methyl)cyclopropanecarboxylate (201 mg), and palladium chloride (dppf) methylene chloride complex (39 mg), and after adding 2N aqueous sodium carbonate solution (0.72 mL) to the mixture, the atmosphere was replaced with nitrogen and the mixture was stirred at 65° C. for 2 hours. To the reaction mixture were added ethyl acetate and water to extract the objective compound, and the organic layer was washed with a saturated brine, and dried over anhydrous sodium sulfate. After concentrating the mixture under reduced pressure, the obtained residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=95:5 to 80:20) to obtain methyl 1-{[(5-{3-chloro-4-[4-(trifluoromethyl)-1-{[2-(trimethylsilyl)ethoxy]methyl}-1H-imidazol-2-yl]phenyl}-4-methylpyridin-2-yl)oxy]methyl}cyclopropanecarboxylate (237 mg).
