Dulenko, A. Kibal'nyi, Yu. Nikolyukin, V. Luk'yanenko, A. Goncharov, S. Sidorova, D. Yufit, Yu. Struchkov] 1-R-3-methylindolo[2,3-c]pyrylium salts react with cyclic secondary amines (morpholine, piperidine, and N-methylpiperazine) to give, depending on the structure of the alkyl substituent R, either 1- (when R=Me) or 3-aminocarbazoles (when R=i-Pr), or mixtures of both (when R=Et). The position of the amino-substituent in 1-morpholino-3,9-dimethylcarbazole has been established by x-ray diffraction examination. Plenum Publishing Corporation, 1990 Dulenko V.
