Abstract

magnified image

A short and facile synthesis of pyrido[2,3‐d]pyrimidine derivatives was accomplished in good yields via the three‐component reaction of aldehydes, alkyl nitriles and aminopyrimidines in water in the presence of triethylbenzylammonium chloride (TEBAC). The structures of these compounds were characterized by elemental analysis, IR and ^1^H NMR spectra and further confirmed by single crystal X‐ray diffraction analysis.
