실험 절차

To a solution of 0.294 g of (RS)-1-(formylmethyl)-3-((4-methylphenyl)aminocarbonylmethyl)-3-(N'-(4-methylphenyl)ureido)indolin-2-one in 50 ml of toluene were added 0.5 ml of ethylene glycol and 10 mg of p-toluenesulfonic acid. The mixture was heated under reflux for 6 hours while azeotropically removing produced water together with toluene. The reaction mixture was washed with saturated aqueous sodium hydrogencarbonate. The organic layer was dried over anhydrous sodium sulfate and concentrated. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=2/1) to give 0.220 g (68%) of the title compound.
