実験手順
To a ice cold solution of 7-nitro-1H-indole-2,3-dione (9 g, 47 mmol) in 2 M aqueous sodium hydroxide (50 mL), 30% hydrogen peroxide (9 mL) was added drop wise. The mixture was warmed to room temperature and stirred overnight. The mixture was carefully acidified by addition of a saturated citric acid solution. The solid precipitate was collected by filtration, washed with water and dried in a vacuum oven to get 6 g of the required product as a yellow coloured solid (70%).
