An efficient synthesis of the title compounds 3-(3-phenyl-7H- [1,2,4]triazole[3,4][1,3,4]thiadiazin-6-yl)-chromen-2-ones (3), by the condensation of 3-(2- bromoacetyl)chromen-2-ones (1) with 4-amino-5-phenyl-4H[1,2,4]triazole-3-thiols (2), is being reported. The reaction has been done under conventional as well as under microwave conditions. The latter procedure has been found to be much more efficient in terms of time and yield. The structures of all the compounds have been established on the basis of their spectral and analytical data.
