実験手順
10% palladium-activated carbon (175 mg) and concentrated hydrochloric acid (1 mL) were added to a solution of (5R)-5-{(E)-2-[4-(cyclopropylsulfonyl)phenyl]-2-[6-methoxy-5-(1H-pyrazol-4-yl)pyridin-2-yl]ethenyl}pyrrolidin-2-one obtained in Example 4-376(1) (175 mg) in methanol (3 mL) in a hydrogen gas stream, and the mixture was stirred at room temperature for five 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-(cyclopropylsulfonyl)phenyl]-2-[6-methoxy-5-(1H-pyrazol-4-yl)pyridin-2-yl]ethyl}pyrrolidin-2-one as a colorless amorphous (129 mg, 73%).
