Reaction Steps

3-Iodo-5-(2-pyridyl)-1-phenyl-1,2-dihydropyridin-2-one (200 mg) synthesized by the same method as mentioned in Referential Example 6, 130 mg of 2-chloro-3-pyridyl boronic acid and 250 mg of cesium carbonate were suspended in 10 ml of dimethylformamide, 40 mg of tetrakistriphenylphosphine palladium were added and the mixture was stirred at 100° C. in a nitrogen atmosphere for 3 hours. After allowing to cool, the reaction solution was poured into water, the mixture was extracted with ethyl acetate, the extract was dried over anhydrous magnesium sulfate, the solvent was evaporated in vacuo and the residue was purified by a silica gel column chromatography (hexane-ethyl acetate system) to give 143 mg of the title compound.
