Procedure

30 mg of 3-(2-cyanophenyl)-1-(piperidin-4-yl)methyl-5-(2-pyridyl)-1,2-dihydropyridin-2-one was dissolved in 2 ml of chloroform. Under ice-cooling, 0.04 ml of triethylamine and 19 mg of benzoyl chloride were added thereto, followed by stirring at room temperature for 2 hours. The reaction solution was diluted with chloroform, and washed with a saturated aqueous solution of sodium hydrogen carbonate and brine. The organic layer was dried over magnesium sulfate, and then evaporated and the residue was purified by silica gel chromatography (ethyl acetate/hexane), to give 25 mg of the title compound.
