Reaction Steps

A suspension of 0.11 g of 3-(2-cyanophenyl)-5-(2-pyridyl)-2 (1H)-pyridone, 0.12 g of phenyl boronic acid 0.1 g of copper acetate and 0.3 ml of triethylamine in 10 ml of methylene chloride was stirred at room temperature for overnight. To this were added 5 ml of concentrated aqueous ammonia, 10 ml of water and 40 ml of ethyl acetate and the organic layer was separated, 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=1:2) to give 0.06 g of the title product as pale yellow powder.
