Reaction Steps

Tetrakistriphenylphosphine palladium (0.15 g) was added to a mixed solution of 0.50 g of 5-(2-pyridyl)-3-bromo-2-methoxypyridine, 0.42 g of 2-(2-cyanophenyl)-1,3,2-dioxaborinate, 0.82 g of cesium carbonate and 20 ml of dimethylformamide and the mixture was stirred at 140° C. in a nitrogen atmosphere for 5 hours. After cooling to room temperature, ethyl acetate was added thereto, the mixture was washed with water and a saturated saline solution and dried over magnesium sulfate. The solvent was concentrated in vacuo and the residue was purified by a silica gel column chromatography (ethyl acetate:hexane=1:3) to give 0.36 of the title compound as pale yellow powder.
