実験手順

3-(Difluoromethoxy)-6-iodo-2-[(4-methoxybenzyl)oxy]pyridine obtained in Reference Example 4-34 (727 mg), cesium fluoride (270 mg), copper iodide (187 mg) and tetrakis(triphenylphosphine)palladium (103 mg) were added to a solution of (5R)-5-[(E)-2-(4-tert-butylphenyl)-2-(tributylstannyl)ethenyl]-1-(2,4-dimethoxybenzyl)pyrrolidin-2-one obtained in Reference Example 4-26 (609 mg) in N,N-dimethylformamide (6 mL), and the mixture was stirred at 75° C. for two hours. Water and ethyl acetate were added to the reaction solution. After filtration through celite, the organic layer was washed with brine. The organic layer dried over anhydrous magnesium sulfate and filtered, after which the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=95:5→1:1) to give (5R)-5-[(E)-2-(4-tert-butylphenyl)-2-{5-(difluoromethoxy)-6-[(4-methoxybenzyl)oxy]-pyridin-2-yl}ethenyl]-1-(2,4-dimethoxybenzyl)pyrrolidin-2-one as a colorless gum (511 mg).
