Popis:	2,6-Diaminotoluene (3a) and 2,6-diamino-p-xylene (3c) led to 2-methyl (and 2,5-dimethyl)-3-acetylamino-phenylhydrazines 5a,b. Fischer indolization of their hydrazones 6a,b and 7a,b derived from 4-methoxycy-clohexanone and 4-piperidone, and subsequent aromatization of intermediate tetrahydrocarbazole derivatives 8a,b and 9a,b allowed us to work out a convenient route to the title compounds.
