実験手順

15 ml of o-dichlorobenzene was added to a mixture of 0.50 g of 2-(4-methylphenyl)-3a,4,10b,10c-tetrahydro-1H-benzofuro[3,2-e]isoindole-1,3(2H)-dione and 0.75 g of DDQ. The mixture was refluxed for 4 hours. The reaction mixture was mixed with 50 ml of chloroform. The resulting mixture was washed with an aqueous 10% potassium carbonate solution and an aqueous saturated sodium chloride solution in this order, and dried over anhydrous magnesium sulfate. The solvent was removed by distillation under reduced pressure. The residue was recrystallized from methanol to obtain 0.18 g (yield: 36%) of 2-(4-methylphenyl)-1H-benzofuro-[3,2-d]isoindole-1,3(2H)-dione as light yellow crystals.
