【 摘 要 】

Pyridines fused with heterocyclic rings are of great interest as both photovoltaic materials and biologically active compounds. The most convenient precursors for these compounds are pyridine-2,3-diamines. In this communication, 3,4-diaminopyridine-2,5-dicarbonitrile was synthesized by the reaction of 2,5-dibromo-3,4-diaminopyridine with copper cyanide; the best yield of the target compound was achieved by heating the reaction mixture in N,N-dimethylformamide at 120 °C for 6 h. The structure of the newly synthesized compound was established by means of elemental analysis, high resolution mass-spectrometry, ¹H, ¹³C NMR, IR, UV spectroscopy and mass-spectrometry.
