A process for the preparation of derivatives of 1,2,5-thiadiazol.

摘要

There are disclosed novel compounds described as 3,4-diamino 1,2,5-thiadiazoles wherein one of the amine functions is connected to a substituted or unsubstituted phenyl or heterocyclic group through a linear connecting group or through a phenylene connecting group. Processes are provided for the preparation of such compounds from amino precursors. The compounds are useful for the suppression of gastric acid secretions in mammals and compositions for such uses are also disclosed.
