Participants

Reaction Steps

A mixture of 5,6-dihydro-4H-pyrrolo[3,2,1-ij]quinoline-1,2dione (5 g) and iodine monochloride (5 g) in acetic acid (30 ml) was refluxed for 5 hours. After cooling, the mixture was poured into ice water and extracted with chloroform. The extract was washed with water, saturated aqueous sodium bicarbonate solution and saturated aqueous sodium chloride solution successively and then dried over anhydrous sodium sulfate. Evaporation of chloroform afforded the title compound. The compound was recrystallized from ethanol to give 6.2 g (73.8%) as dark red needles.
