An efficient and user-friendly synthesis for a series of N-heteroaryl nitriles is described. This process is based on the CuI catalyzed cyanation of N-heteroaryl bromides with K4[Fe(CN)6] in the presence of N-isopropylimidazole and N,N-dimethylethylenediamine. The results show that the reaction has good to high yields.

Key words: potassium hexacyanoferrate(II), cyanation, N-isopropylimidazole, N,N-dimethylethylene- diamine, N-heteroaryl nitrile
