benzisoxazolyl-3-acetic acid and thiosemicarbazide. Reaction of 3 with bromine in glacial acetic acid in the presence of anhydrous sodium acetate yielded the corresponding 5-bromo derivatives (4a–f). While compound 3 furnished the 5-nitroso derivatives (5a–f) on refluxing with sodium nitrite solution. Thiocyanato derivatives (6a–f) were obtained by treating the imidazothiadiazole 3 with bromine and potassium
