Procedure

3.42 g of 3-(2-cyanophenyl)-1-phenyl-5-(tri-n-butyl stannyl)-1,2-dihydropyridin-2-one, 1.57 g of 5-acetoxy-2-chloropyridine and 352 mg of tetrakistriphenylphosphine palladium were added to 40 ml of xylene, and the mixture was stirred at 120° C. in a nitrogen atmosphere for 8.5 hours. The reaction mixture was refined by silica gel chromatography (ethyl acetate/hexane-based solvent), to obtain 953 mg of the subject compound.
