The reactions of 2-dimethyliminomethyl-3-(p-nitrophenyl)aminoindole chloride with compounds with an active methylene center have been studied. A series of derivatives of δ-carboline have been synthesized. By the reaction of 3-ethoxycarbonyl-2-methyl-l-p-nitrophenylpyrido[3,2-b]indolinium chloride with the diethyl acetal of DMF the corresponding 2-dimethylaminovinyl derivative was synthesized which was converted into 5-p-nitrophenyl-1-oxo-1,10-dihydropyrano [3′,4′:5,6]pyrido[3,2-b]indol-5-ium chloride in the presence of acid.
