実験手順

10% palladium-activated carbon (60 mg) and acetic acid (2 mL) were added to a solution of (5R)-5-{(E)-2-(4-chlorophenyl)-2-[6-methoxy-5-(1H-pyrazol-4-yl)pyridin-2-yl]ethenyl}pyrrolidin-2-one (122 mg) in methanol (3 mL) in a hydrogen gas stream, and the mixture was stirred at room temperature for 20 hours. The reaction solution was filtered through celite, and then the solvent was evaporated under reduced pressure. Saturated aqueous sodium bicarbonate was added to the residue, followed by extraction with chloroform. The solvent was evaporated from the organic layer under reduced pressure to give a crude product of (5R)-5-{2-(4-chlorophenyl)-2-[6-methoxy-5-(1H-pyrazol-4-yl)pyridin-2-yl]ethyl}pyrrolidin-2-one as a yellow oil (77 mg).
