実験手順

EDC (834 mg), HOBT (588 mg) and IPEA (2.03 mL) were added to a suspension of (E)-3-[6-methoxy-5-(4-methyl-1H-imidazol-1-yl)pyridin-2-yl]acrylic acid trifluoroacetate (1.42 g) and 1-amino-3-(2-trifluoromethylphenyl)piperidin-2-one (750 mg) in DMF (30 mL). After stirring at room temperature for 14 hours, a saturated sodium bicarbonate solution and ethyl acetate 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 (carrier: Chromatorex NH; elution solvent: ethyl acetate-methanol system) to obtain 1.23 g of the title compound. The property values of the compound are as follows.
