Reaction Steps
5-Bromo-1,3,4-thiadiazole-2-carbonitrile To a solution of 5-bromo-1,3,4-thiadiazole-2-carboxamide and Et3N (2.3 equiv) in THF (0.5 M) at 0° C. was added TFAA (1.1 equiv). The mixture was then warmed to room temperature and stirred for 30 min, then the solvent was evaporated in vacuo. The resulting residue was diluted with water. The resulting precipitate was collected, washed with water, and dried to give the title compound.
