Procedure

In 30 ml of dichloromethane was dissolved 0.5 g of (+)-1-(2,2-diethoxyethyl)-3-hydroxycarbonylmethyl-3-(N′-(3-methoxyphenyl)ureido)indolin-2-one, and 0.22 g of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride and 0.20 g of p-toluidine were successively added thereto. After stirring the mixture for 9 hours, the reaction mixture was diluted with ethyl acetate and washed successively with dilute hydrochloric acid and saturated aqueous sodium hydrogencarbonate. The organic layer was dried over anhydrous sodium sulfate and concentrated. The crude product was purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to yield 0.49 g of the title compound as a white powder.
