4-Aryl-6-methyl-2-pyrimidinone-5-carbohydrazide derivatives have been synthesized from the reaction of different dihydropyrimidinone with hydrazine hydrate. These compounds upon microwave irradiation undergo clean and facile cyclization with chloroacetamide, chloroacetyl chloride and triethylorthoformate and led to the formation of 3-(6-methyl-2-oxo-4-substituted phenyl-1,2,3,4-tetrahydropyrimidin-5-yl)-1,6-dihydro-1,2,4-triazin-5(2H)-one, 4-(6-methyl-2-oxo-4-substitutedphenyl-1,2,3,4-tetrahydropyrimidin-5-yl) tetrahydropyridazine-3,6-dione, 6-methyl-5-(5-oxo-4,5-dihydro-1H-pyrazol-4-yl)- 4-substitutedphenyl-3,4-dihydropyrimidin-2(1H)-one and their substituted derivatives respectively, in quantitative yield. Structures of these newly synthesized compounds were established on the basis of spectra and analytical data.
