DMF (3 mL) and TEA (0.06 mL) were added to (4-fluorophenyl)-{5-{(E)-2-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]vinyl}-4H-[1,2,4]triazol-3-yl}amine synthesized in Example 162 (44 mg), and the reaction solution was stirred at room temperature for 10 minutes. Acrylic acid chloride (0.01 mL) was added to the reaction solution at room temperature, and the reaction solution was stirred at room temperature for one hour and at 60° C. for two hours. TEA (0.03 mL) and acrylic acid chloride (0.01 mL) were added to the reaction solution at 60° C., and the reaction solution was stirred at 60° C. for four hours. The reaction solution was left to cool to room temperature and then diluted with ethyl acetate and washed with a saturated sodium bicarbonate solution and a saturated sodium chloride solution. The resulting organic layer was dried over magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (carrier: Chromatorex NH; elution solvent: heptane-ethyl acetate system, then ethyl acetate-methanol system) and further purified by silica gel column chromatography (elution solvent: heptane-ethyl acetate system, then ethyl acetate-methanol system) to obtain 6 mg of the title compound. The property values of the compound are as follows.
