- Synthesis of some functionalized thiazolo[3,2-b][l,2,4]triazoles
-
A facile synthesis of some 6-aminothiazolo[3,2-b][l,2,4]triazole-5- carbonitriles in good yields has been developed through base catalyzed cyclocondensation of l,2,4-triazole-3-thiones with bromomalononitrile. In case of phenyl derivative, hydrolysis of the cyano group into amide and subsequent cyclocondesation with benzoyl chloride afforded to the novel tricyclic compound 2,6-diphenyl[l,2,4]triazolo- [5',l':2,3][l,3]thiazolo[4,5-d]pyrimidin-8(7H)-one.
