Reaction Steps

27 mg of 3-bromo-5-(2-pyridyl)-1-phenyl-1,2-dihydropyridin-2-one and 130 mg of 1-adamantylamine were dissolved in 10 ml of dimethylformamide. To the mixture was added 20 mg of sodium hydride, followed by stirring at 130° C. in nitrogen atmosphere. After the reaction solution was cooled to room temperature, a saturated aqueous solution of ammonium chloride and water were added thereto, followed by extracting with ethyl acetate. The organic layer was washed with brine and dried over anhydrous magnesium sulfate. The solvent was evaporated, and the residue was purified by silica gel chromatography (hexane/ethyl acetate system), to give 3 mg of the title compound.
