ABSTRACT:
The present invention provides novel substituted sulfooxy-pyrimidinium, -pyridinium, and -triazinium hydroxide inner salts. These compounds are useful for the treatment of hypertension and peripheral vascular diseases. They are formed by reacting the corresponding aminopyrimidine, aminotriazine, and aminopyridine N-oxides with a latent sulfate source such as pyridinium-sulfur trioxide complex, triethylamine-sulfur trioxide complex, chlorosulfonic acid or chlorosulfuryl chloride.
