実験手順
To a solution of 8-chloro-5,6-dihydro-4-phenyl-4H-pyrrolo-[3,2,1-ij]quinoline-1,2-dione (3.4 g) and sodium hydroxide (2 g) in water (100 ml) was added 35% aqueous hydrogen peroxide solution (5 ml) and stirred at room temperature for an hour. The reaction mixture was acidified slightly by adding concentrated hydrochloric acid, the resulting precipitate was collected by filtration, washed and dried to give the title compound (3.17 g, 96.7%) as yellow crystals. This crystals was recrystallized from ethanol to pale yellow needles, mp 199°-200 ° C.
