Abstract

The present work reports the synthesis of a new compound 2-amino-4,6-di(pyridin-4-yl)benzene-1.3.5-tricarbonitrile as a result of the reaction of two moles of 2-(pyridin-4-ylmethylene)malononitrile with one mole of malononitrile in the presence of methylpiperazine as a catalyst. The structure of the obtained product was confirmed by NMR and X-ray. A plausible reaction mechanism is presented.
