Synthesis of some pyrimidine derivatives from-4- acetyl pyridine

Abstract

Chalcones compounds(1-4) were prepared from - 4 - acetyl pyridine with different aromatic aldehyde benzaldehyde in the presence of KOH solution . The compounds (1-4) were reacted with thiourea to give compounds (5-8), with guanidine to give compounds (9-12). and with urea to give the compounds (13-16), in the presence of KOH as abasic. The prepared compounds were identified using melting point apparatus , F T. IR spectro photo meter and (1H-NMR) spectrometer for some compounds .
