The cyclization of 5-formylmethylamino-8-chlorolepidine and subsequent alkylation gave a 1,6-dimethyl-7-chloro-1,6-diazaphenalenium salt, one of the representatives of compounds previously called aromatic cyanines. The spectral characteristics and chemical properties of this salt are in close agreement with the results of calculations by the Hückel MO method.
