Procedure
A mixture of 9.9 g. of 9-carbethoxymethyl-3-(dimethylamino)-1,2,3,4-tetrahydrocarbazole hydrochloride (Example 14) in 50 ml. of 6-N hydrochloric acid was heated on a steam bath for one and one-half hours, cooled, and the resulting solids were collected by filtration to give, after recrystallization from ethyl alcohol-water, 6.26 g. of 3-(dimethylamino)-9-carboxymethyl-1,2,3,4-tetrahydrocarbazole hydrochloride, m.p. 316°-319° C.
