electrophilicity of the bromine atom, thus leading to enhanced reactivity as a brominating reagent. Differing intermediate indazole species have been observed depending upon the electronic nature of the indazole substituents. The indazole-containing pharmaceutical Benzydamine has been brominated in good yield using the optimized reaction conditions as a demonstration of the bromination method.
