実験手順

Copper cyanide (27 mg) was added to a solution of (5R)-5-[(E)-2-(5-bromo-6-methoxypyridin-2-yl)-2-(4-tert-butylphenyl)ethenyl]-1-(2,4-dimethoxybenzyl)pyrrolidin-2-one obtained in Reference Example 4-42(1) (90 mg) in N,N-dimethylformamide (5 mL), and the mixture was stirred at an external temperature of 180° C. for two hours. Water was added to the reaction solution, followed by extraction with ethyl acetate. The organic layer was washed with saline, dried over magnesium sulfate and filtered. The solvent was then evaporated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=4:1→1:1) to give 6-{(E)-1-(4-tert-butylphenyl)-2-[(2R)-1-(2,4-dimethoxybenzyl)-5-oxopyrrolidin-2-yl]ethenyl}-2-methoxypyridine-3-carbonitrile (32 mg, 40%).
