Versuchsvorschrift

A slight excess of 7.5N alcoholic hydrogen chloride was added to a solution of 2.7 g. of 6-chloro-1,2,3,4-tetrahydrocarbazole-2-carboxylic acid dimethylaminoethyl ester in 15 ml. of ethanol. Ether was added until crystallization was induced and the resulting precipitate was filtered and washed with a mixture of ethanol and ether. Upon drying, 2.8 g. of the salt, 6-chloro-1,2,3,4-tetrahydrocarbazole-2-carboxylic acid dimethylaminoethyl ester hydrochloride, m.p. 201°-203° , was obtained.
