The reaction of β-keto esters with aminoguanidine afforded 2,3-diamino-4 (3H)-pyrimidones (IV), which were employed for the cyclization to 5,8-dihydro-s-triazolo [1,5-a] pyrimidin-5-ones (V) and 1,2-dihydro-3-methyl-6H-pyrimido [1,2-b] as-triazine-2,6-diones (VIII). Further treatment of β-keto esters with thiosemicarbazide gave 3-amino-4 (3H)=oxo-2 (1H)-pyrimidinethiones (XII). 7-Methyl-5H-1,3,4-thiadiazolo [3,2-a] pyrimidin-5-one (XIV) was derived from the 6-methyl derivative of XII.
