A very simple and efficient procedure for the synthesis of novel 2-hydroxy-4H-pyrimido(1,2-a]pyrimidin-4-ones is described. Title compounds were obtained from the room temperature reaction of 2-aminopyrimidine and its substituted derivatives with bis(2,4,6-trichlorophenyl) malonates. High product yields were observed under optimized conditions. Applicability and reactivity of a range of substituted
