Methods are described for the preparation of secondary heterocyclic amines containing a pyridine nitrogen atom in the α position relative to the amino group.Compounds of this class were prepared: a) from α-hetaryl halides and α-hetarylamines in presence of barium oxide ( the process is accompanied by intramolecular cyclization, leading to the formation of condensed imidazoles); b) by the cyclization of heterylthioureas with a bromo acetal; c) by the reactions of 2-(methylthio)benzindole hydiodide with α-heterylamines.Secondary heterylamines containing a benzindole system exist in the imino form.
