Heterocyclic Variants of the Purine System. I Derivatives of Thiazolo-1,2,4-triazine
Jacobsen, Noel W.,Philippides, Athena E.
, p. 491 - 499 (2007/10/02)
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
