Procedure
100 mg of 3-bromo-5-(2-pyridyl)-1-phenyl-1,2-dihydropyridin-2-one and 58 mg of phenol were dissolved in 10 ml of dimethylformamide, to which 84 mg of potassium carbonate and 6 mg of copper iodide were added, and the mixture was stirred at 150° C. for 5 hours. The reaction solution was cooled to room temperature, to which ammonia water was added, and extracted with ethyl acetate. The organic layer was washed with saturated saline water and dried by magnesium sulfate anhydride, and the solvent was distilled off under a vacuum. The residue was refined by silica gel chromatography (hexane/ethyl acetate-based solvent), to obtain 66 mg of the subject compound.
