Reaction Steps

To a solution of 5-methoxyisatin (15.0 g, 84.7 mmol) in DMF (100 mL), sodium hydride (5.1 g, 127 mmol) and benzyl bromide (12.1 mL, 101.6 mmol) were added at 0° C., and the resulting mixture was stirred for 1 hour. Water was added thereto, and the resulting solution was extracted with ethyl acetate. The resulting organic phase was washed with saturated ammonium chloride aqueous solution and then with saturated sodium chloride solution, dried over anhydrous sodium sulfate, and concentrated to obtain the aimed product (yield: 96%).
