Procedure

To 56 mg of 3-(2-cyanophenyl)-5-(2-pyridyl)-1-(3-hydroxyphenyl)-1,2-dihydropyridin-2-one were added 1 ml of acetic anhydride and 1 ml of pyridine and the mixture was stirred at room temperature for one night. The reaction solution was concentrated in vacuo and purified by an NH silica gel chromatography (hexane-ethyl acetate system) to give 30 mg of the title compound.
