EDC (667 mg), HOBT (470 mg) and IPEA (1.01 mL) were added to a suspension of (E)-3-[6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl]acrylic acid (300 mg) and 1-amino-3-(3,4,5-trifluorophenyl)piperidin-2-one (368 mg) in DMF (10 mL). The reaction solution was stirred at room temperature for 15 hours. Then, water and ethyl acetate were added to the reaction solution, and the organic layer was separated. The resulting organic layer was washed with brine, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: ethyl acetate-methanol system) to obtain 508 mg of the title compound. The property value of the compound is as follows.
