3,5-diamino-1,2,4-oxidiazoles as gastric secretion inhibitors

摘要

Novel diamino oxadiazoles, wherein one of the amine functions is connected to a basicly-substituted heterocyclic group through a linear or cyclic connecting group, which are useful for the suppression of gastric acid secretions in mammals. Compositions employing these compounds and processes for the preparation of such compounds from known N-cyano-S-methylisothiourea precursors by treatment with hydroxylamine and for alkylation of amine groups are also disclosed.
