Procedure

A suspension of 0.62 g of (RS)-1-(2,2-diethoxyethyl)-3-((4-methylphenyl)aminocarbonylmethyl)-3-(N'-(4-nitrophenyl)ureido)indolin-2-one and 20 mg of 5% Pd/C in 100 ml of ethanol was stirred at room temperature for 12 hours under a hydrogen atmosphere. The reaction mixture was filtered through Cerite, and the filtrate was concentrated. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=1/1) to give 0.33 g (57%) of the title compound.
