Procedure

A solution of 2-(4-fluorophenyl)-4-hydroxy-2-methoxybutyric acid hydrazide (40 mg) in ethanol (1.6 mL) was added to a solution of ethyl(E)-3-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]acrylimidate dihydrochloride (65 mg) and TEA (0.12 mL) in ethanol (0.7 mL), and the reaction solution was stirred at 75° C. for two days. The reaction solution was left to cool to room temperature. Then, ethyl acetate and water were added to the reaction solution, and the organic layer was separated. The organic layer was washed with brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography (elution solvent: heptane-ethyl acetate-methanol system) to obtain 38 mg of the title compound. The property value of the compound is as follows.
