Reaction Steps

A mixture of 5,6-dihydro-4-phenyl-4H-pyrrolo[3,2,1-ij]-quinoline-1,2-dione (3.1 g) and N-chlorosuccinimide (1.89 g) in dimethylformamide (DMF; 50 ml) was stirred at 80 ° C. for an hour. After cooling, the mixture was concentrated under reduced pressure and to the resulting residue was added chloroform (500 ml). The organic layer was washed with water and saturated aqueous sodium chloride solution, dried over sodium sulfate and concentrated under reduced pressure to give the title compound (3.4 g, 96.8%). This crystals was recrystallized from acetonitrile to give dark reddish crystals, mp 173°-174 ° C.
