An efficient methodology for the preparation of aminobutyl-bromo-terpyridine is described using a preformed imine prepared from a gem-dibromomethyl terpyridine derivative and the primary amine and further reduced to the secondaryamine. Alkylation with pyridine, bipyridine, or terpyridine residues in the presence of a mineral base provides highly functionalized asymmetrical and symmetrical N-heterocyclic
