An efficient and convenient method was developed for the formation of polysubstituted thiazolo[3,2-b][1,2,4]triazoles through C-5 (het)arylation. The direct C-H activation protocol giving access to di- and trisubstituted derivatives in excellent yields was optimized. The method is suitable for use with a wide range of (hetero)aryl bromides, and allows access to a collection of C-5,6 bis(het)aryl derivatives with full regioselectivity. The results are supported by a full description of all final compounds, and X-ray crystallographic data confirmed that the spectroscopic analyses were interpreted correctly. Copyright
