A practical Pd(PPh3)4/DBU catalytic system for the synthesis of pharmaceutically relevant aminopyridine nitrile intermediates, as well as a variety of other aryl nitriles using non-toxic K4[Fe(CN) 6] has been developed. The key features of our new protocol for cyanation lie in that the reaction can be carried out with readily available Pd(PPh3)4 under mild and green conditions, even without the assistance of other ligands.

The present invention relates to a process for preparing optionally substituted aromatic or heteroaromatic nitriles starting from haloaromatics. These are reacted in a copper-catalysed reaction with potassium hexacyanoferrate(II) or potassium hexacyanoferrate(III) in the presence of heteroaromatic amines.

A general protocol for the cyanation of aryl halides with the nontoxic cyanide source K4[Fe(CN)6] using copper catalysis and a ligand system based on 1-alkylimidazoles is presented. The advantages of this system are the high selectivity, a unique substrate range, easy handling, and inexpensive reagents.
