실험 절차

Chlorotrimethylsilane (0.1 ml) was added to a suspension of 0.20 g of 3-(2-cyanophenyl)-5-(2-pyridyl)-2-methoxypyridine and 0.12 g of sodium iodide in 10 ml of acetonitrile and the mixture was stirred at room temperature for 3 hours. A saturated sodium bicarbonate solution was added to the mixture followed by extracting with ethyl acetate. The ethyl acetate layer 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=1:1) to give 0.11 g of the title compound in pale yellow powder.
