Reaction Steps

480 mg of ethyl 2-[(R)-2-[[(S)-2-[2-(6-cyano-1-ethylindol-2-yl)ethyl]pyrrolidinyl]carbonyl]pyrrolidinyl]acetate obtained in Example 60-a) was dissolved in methanol. 304 mg of hydroxylamine hydrochloride and 695 mg of sodium carbonate were added and the reaction solution was refluxed overnight with stirring. After water was added, the reaction solution was extracted two times with dichloromethane. The extract was dried over MgSO4 and distilled under reduced pressure. The residue was purified with silica gel column chromatography [eluent: dichloromethane/methanol(20:1)] to obtain 27 mg of the title compound.
