4-Aryl-5-carboethoxy-6-methyl-1,2,3,4-tetrahydropyrimidin-2-ones have been synthesized from easily available starting materials. The carboethoxy group at the C5-position of the pyrimidine ring is converted to corresponding hydrazide which in turn is condensed with cyclising agents such as aromatic aldehydes, CS2 etc. to give fused heterocycles. The fused heterocycles are then subjected to phenacylation to give N3-phenacylpyrimido-heterocycles in excellent yield. In a slightly modified way, uracil derivatives are condensed with ethyl bromoacetate to give N3-β-ethoxycarbonyl derivatives. The hydrazide derivatives of these N3-β-ethoxycarbonyl derivatives subsequently react with 1,2-diketones to give corresponding pyrimido pyridazine derivatives.
