참여 물질

반응 단계

A stirred mixture of acetic acid 1-(5-fluoro-2-oxo-2,3-dihydro-1H-indol-6-ylcarbamoyl)-ethyl ester (720 mg, 2.45 mmol) in methanol (5 ml) and water (5 ml) was added with sodium hydroxide (200 mg, 50 mmol). The resulting mixture was stirred at room temperature overnight and concentrated under reduced pressure. The residue was extracted with ethyl acetate (100×3) and water (100×3). The organic extracts were dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure to give N-(5-fluoro-2-oxo-2,3-dihydro-1H-indol-6-yl)-2-hydroxy-2-methyl-propionamide (220 mg, 35.6%) as a white solid.
