The novel heterocycles, Ethyl -6- methyl- 2- oxo- 4- (2- phenyl -1,2,3-triazol-4-yl) - 3,4 dihydropyrimidine-5- carboxylate (4) have been synthesized from 1,3-dicarbonyl compounds, appropriate aldehyde and urea or thiourea under green method. 6– Methyl – 4 –(2- phenyl -1,2,3-triazol-4-yl) –5-(5-substituted phenyl -1, 3, 4–oxadiazol -2- yl) -3, 4-dihydropyrimidine-2(1H)-one (6 a-g) have been synthesized from comp. (4) using hydrazine hydrate, substituted benzoic acid, phosphorous oxychloride by microwave irradiation reported in literature. Above synthesized heterocycles 6 a-g irradiated under microwave with hydrazine hydrate to get amino triazole derivatives of dihydropyrimidine 7 a-g. The structures of newly synthesized compounds have been confirmed by IR and 1H NMR spectra.
