Versuchsvorschrift

IPEA (1.5 mL), 1-amino-3-(3,4-difluorophenyl)piperidin-2-one (420 mg) and BOPCl (0.53 g) were added to a solution of (E)-3-[3-methoxy-4-(4-methyl-1H-imidazol-1-yl)phenyl]acrylic acid (450 mg) in methylene chloride (15 mL) at room temperature, and the reaction solution was stirred at room temperature for three hours. Water was added to the reaction solution, followed by extraction with chloroform. The resulting extract washed with 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) to obtain 572 mg of the title compound. The property value of the compound is as follows.
