実験手順
To a solution of 2-bromo-5-((2-phenoxybenzyl)oxy)pyridine (1.0 g) in dimethylformamide (7 ml), 1.26 g of ethyl (2E)-3-(tributylstannyl)acrylate and 350 mg of tetrakis triphenylphosphine palladium were added, and the reaction solution was stirred overnight at 100° C. under nitrogen atmosphere. The reaction solution was cooled, then 15 ml of a saturated aqueous potassium fluoride solution was added, and the reaction solution was stirred for 1 hour, followed by removing insoluble matters by filtration through Celite and the filtrate was concentrated under reduced pressure. The residue obtained was diluted with water, extracted with diethyl ether, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and the residue obtained was purified by silica gel column chromatography (eluent: ethyl acetate/hexane (0:100-25:75-30:70)) to afford the title compound as a yellow solid.
