Reaction Steps

40 mg of 3-amino-1-phenyl-5-(2-pyridyl)-1,2-dihydropyridin-2-one and 10 mg of sodium hydride were added to 1 ml of toluene, to which 30 mg of benzyl chloride was added dropwise at 70° C. The mixture was stirred for 30 minutes, and heated for 1 hour under reflux. The reaction mixture was left to cool to room temperature, diluted with ethyl acetate, and washed with a water and a saturated saline water. The organic layer was dried by magnesium sulfate, and refined by NH silica gel chromatography (ethyl acetate/hexane-based solvent), to obtain 13 mg of the subject compound.
