Sodium hydrate (containing mineral oil at 60%, 6 mg) was added to a solution of 3-(4-fluorobenzyl)-5-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-4H-[1,2,4]triazole (18 mg) in THF (1 mL), and the reaction solution was stirred at room temperature for 30 minutes. Iodomethane (20 mg) was added to the reaction solution, and the reaction solution was then stirred at room temperature for 1.5 hours. Ethyl acetate and saturated sodium bicarbonate water were added to the reaction solution, and the organic layer was separated. The resulting organic layer was dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: ethyl acetate:ethanol=9:1) to obtain 6 mg of 5-(4-fluorobenzyl)-3-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-1-methyl-1H-[1,2,4]triazole and 2 mg of 3-(4-fluorobenzyl)-5-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-1-methyl-1H-[1,2,4]triazole.
