To 100 ml of toluene were added 1.12 g of 9-acetylcarbazole-3,4-dicarboxylic anhydride and 1.06 g of N,N-dimethylethylenediamine. The mixture was azeotropically refluxed for 2 hours. The solvent was removed by distillation under reduced pressure. The residue was recrystallized from n-propanol to obtain 960 mg (yield: 78%) of N-(2-dimethylaminoethyl)-carbazole-3,4-dicarboximide as light yellow needles.
