Reaction Steps

3-[2-[N-(Benzyloxycarbonyl)-N-(2-hydroxyethyl)amino]ethyl]-2,3-dihydro-1H-indol-2-one (256 mg) was dissolved in dichloromethane (5 ml), added with triethylamine (0.20 ml) and methanesulfonyl chloride (0.11 ml) with ice cooling and stirred at room temperature for 1.5 hours. The reaction mixture was added with water (5 ml) and extracted twice with dichloromethane (5 ml). The organic layer was dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (elution solvent: hexane:ethyl acetate=1:2) to obtain 158 mg of the title compound. Yield: 51%.
