Diaza-2C-DFLY, also known as 8-(aminoethyl)-1,5-dihydropyrrolo[2,3-f]indole, is a chemical compound of the phenethylamine family related to the FLY group of psychedelic drugs. It is a tricyclic benzodipyrrole or pyrroloindole derivative. The compound is the analogue of 2C-DFLY in which the oxygen atoms within the dihydrofuran rings have been replaced with nitrogen atoms. Diaza-2C-DFLY is a sort of hybrid chemical structure between the phenethylamine FLY compounds and tryptamines. In addition, it may be considered a substituted partial ergoline. Diaza-2C-DFLY does not yet appear to have been synthesized or studied. It was first described in the scientific literature, as a theoretical compound of interest, by Daniel Trachsel in 2013. Various related theoretical compounds were also discussed.
