Starting from 2,5‐bisarylidenecyclopentanone and malononitrile (1:1) several novel pyrindine derivatives were synthesized by a facile and convenient one‐pot reaction using sodium ethoxide in absolute ethanol at room temperature. The structure of the reaction products was unambiguously deduced ftom their infrared, 1 H‐nuclear magnetic resonance spectroscopy, elemental analysis and single crystal X‐ray crystallography.
