1-Piperidinecarbonyl chloride → HCID 86746368, compound

Participants

Reaction Steps

In 8 ml of pyridine was dissolved 200 mg of N-(2-dimethylaminoethyl)-6-hydroxycarbazole-3,4-dicarboximide. There was added 460 mg of 1-piperidylcarbonyl chloride. The mixture was stirred at room temperature overnight. The solvent was removed by distillation under reduced pressure. The residue was mixed with 10 ml of isopropyl alcohol. The mixture was stirred at room temperature for 10 minutes. The resulting crystals were collected by filtration and dried to obtain 180 mg (yield: 62%) of N-(2-dimethylaminoethyl-6-(1-piperidyl-carbonyloxy)carbazole-3,4-dicarboximide hydrochloride as yellow crystals.
