Heterocyclic Variants of the Purine System. I Derivatives of Thiazolo-1,2,4-triazine

Derivatives of the thiazolo-1,2,4-triazine ring system were prepared from appropriate 6-acylamino-1,2,4-triazin-5(2H)-ones by thiation and cyclization with phosphorus pentasulfide. 5-Methylthio-1,2,4-triazin-6-amines also gave thiazolo-1,2,4

Synthesis of 1,2,4-Triazines, XI. - Synthesis and Reactions of 6-Amino-1,2,4-triazin-5-ones and 6-Amino-1,2,4-triazine-5-thiones

6-Amino-1,2,4-triazin-5(2H)-ones 3 are prepared by reaction of thioxamidates 1 with amidrazones 2.Reaction of 3 with phosphorus pentasulfide affords the 6-amino-1,2,4-triazine-5(2H)-thiones 4.Some reactions of these compounds are described.
