Abstract
Chalcones afford a facile route of access to many of the heterocyclic systems containing oxygen and nitrogen. An attempt is therefore made to synthesize chalcones from 3-acetylpyridine by reaction with either aromatic or heteroaromatic aldehyde using Claisen-Schmidt condensation. The resulting chalcones after purification and characterization by physical and spectral methods have been successfully converted into substituted pyrimidines by reaction with guanidine hydrochloride. All these compounds were characterized by means of their IR, 1 H NMR, 13 C NMR and mass spectral data.
