Synthesis of 1,2,3-Thiadiazolo (5,4-d)pyrimidines. -Condensation of 5-aminothiadiazole-4-carboxamides (I) or (IV) with orthoesters provides the target thiadiazolopyrimidines in moderate to good yield. Attempts to synthesize this heterocyclic system by three-component condensation of readily availab
