Abstract
The bromination of 3-amino-1,2,4-benzothiadiazine-1,1-dioxide (1) in N,N-dimethylformamide has been studied. Depending on the operating conditions the reaction produces 7-bromo-3-amino-1,2,4-benzothiadiazine-1,1-dioxide (II) or 5,7-diabromo-3-amino-1,2,4-benzothiadiazine-1,1-dioxide (III). Derivatives halogenated at the nitrogen were not isolated in any of the experiments.
