Procedure

In 10 ml of chloroform was dissolved 500 mg of N-(2-dimethylaminoethyl)-carbazole-3,4-dicarboximide. Into the solution was introduced hydrogen chloride gas with ice cooling, until the solution was saturated with the gas. The resulting solution was stirred for 10 minutes with ice cooling. The resulting crystals were collected by filtration and dried to obtain 450 mg of N-(2-dimethylaminoethyl)-carbazole-3,4-dicarboximide hydrochloride as yellow crystals.
