Reaktionsschritte

100 mg of 3-bromo-1-phenyl-5-(pyridin-2-yl)-1,2-dihydropyridin-2-one, 55 mg of phenylacetylene, 1 mg of copper (I) iodide and 4 mg of dichlorobis(triphenylphosphine) palladium were added to a mixed solvent of 1.5 ml of triethylamine and 1 ml of dimethylformamide, and stirred at 50° C. in a nitrogen atmosphere for a night. The reaction mixture was distributed into the ethyl acetate and water layers. The organic layer was washed with water, dried and concentrated, and the residue was refined by silica gel chromatography (ethyl acetate/hexane-based solvent), to obtain 7 mg of the subject compound.
