An efficient and simple method was developed for the synthesis pyrimidine-5-carboxamides using UO 2 (NO 3 ) 2 .6H 2 O catalyst under conventional and microwave irradiation. The synthesis of dihydropyrimidine using uranylnitrate had shown many advantages such as easy work up, shorter reaction times and higher yields using acetonitrile as a solvent. The structures of the synthesized compounds were confirmed
