Reaction Steps

In 30 ml of methanol was dissolved 60 mg of N-(2-dimethylaminoethyl)-6-nitrocarbazole-3,4-dicarboximide. Thereto was added 30 mg of 5% palladium-carbon. The mixture was subjected to catalytic reduction in a hydrogen atmosphere at room temperature at atmospheric pressure for 5 hours. Thereto was added Celite, and the resulting mixture was filtered. The filtrate was concentrated under reduced pressure. The residue was mixed with diethyl ether, and the mixture was stirred for 10 minutes. The resulting crystals were collected by filtration and dried to obtain 30 mg (yield: 55%) of N-(2-dimethylaminoethyl)-6-aminocarbazole-3,4-dicarboximide as orange crystals.
