Bis-1,3(N-3',6'-dimethylcarbazolyl)propane. A mixture of 25.0 g (157 mmol) of p-methylphenylhydrazine hydrochloride and 17.6 g (157 mmol) of 4-methylcyclohexanone was stirred overnight in 75 ml of 95% ethanol. The mixture was cooled to 0° C, filtered, and the product recrystallized from ethanol/water to give 20.7 g (66%) of 3,6-dimethyl-1,2,3,4-tetrahydrocarbazole, mp 118.5°-20° C (lit. mp 112° C).
