실험 절차

Anisole (1 mL) was added to a solution of 6-{(E)-1-(4-tert-butylphenyl)-2-[(2R)-1-(2,4-dimethoxybenzyl)-5-oxopyrrolidin-2-yl]ethenyl}-3-methoxypyridin-2(1H)-one (65 mg) in trifluoroacetic acid (2 mL), and the mixture was stirred at 80° C. for nine hours. The solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform:methanol=1:0→9:1) to give the title compound as a colorless powder (29 mg).
