efficient multicomponent protocol has been developed for the synthesis of various poly-substituted 2-(pyridin-2-yl)imidazoles from 2-cyanopyridine, corresponding aromatic aldehydes, and NH4OAc/primary amine. Notably, tri-substituted 2-(pyridin-2-yl)imidazoles were highly yielded when aromatic primary amines were used as substrates, but both di- and tri-substituted 2-(pyridin-2-yl)imidazoles were obtained
