Alkylation of α,ω-alkanediamines and their N,N′-disubstituted derivatives with 2-(chloromethyl)pyridinium chloride in the presence of hexadecyltrimethylammonium chloride as a phase-transfer catalyst gave conveniently the corresponding N,N,N′,N′-tetrakis (2-pyridylmethyl)-α,ω-alkanediamines in good yields. N,N′-Bis(2-pyridylmethyl)-N,N′-bis (2-thienylmethyl)-1,2-ethanediamine was similarly obtained.
