%X .Some representative derivatives of the new thiazolo [4,5- e]-1,2,4-triazine ring system were prepared from 5-acylamino-1,2,4-triazin-6(1 H)-ones by heating with phosphorus pentasulfide in pyridine. Further derivatives of the biheterocyclo system were also made from 6-methylthio-1,2,4-triazin-5-amines by heating with carbon disulfide or phenyl isothiocyanate.
