The first quinolyl substituted 1,2,4‐triazole, 3,5‐bis(2‐quinolyl)‐1,2,4‐triazole (4), was synthesized from 2‐cyanoquinoline (1) through an intermediate 2‐quinolylhydrazidine (2) with 60.4% yield in a simple way. In the synthetic process of 4, another new intermediate, 1,4‐diamino‐1,4‐bis(2‐quinolyl)‐2,3‐diaza‐1,3‐butadiene (3) was obtained in a yield of 81.5%. Additionally, the absolute configurations of both 3 and 4 were determined by X‐ray crystallography. J. Heterocyclic Chem., 2010.
