To a solution of 6-bromo-4-fluoroindoline-2,3-dione (7.4 g, 31.8 mmol) in 1 M NaOH (100 mL) was added 38% H2O2 (13 mL) dropwise. The resulting solution was stirred at rt for 2 h. The mixture was filtered and the filtrate was acidified using hydrochloric acid (2 N) till pH became around 2. The precipitate was formed and filtered, washed with water, dried under vacuum to give 2.8 g of the desired product. MS (ESI): 232, 234 (MH−).
