Ethoxycarbonyl isothiocyanate reacts additively with hydrazine, ethoxycarbonylhydrazine, as well as amino- and 1,2-diaminoguanidine.Simultaneous or subsequent cyclisation of the resulting 1:1- or 2:1-adducts in acidic or alkaline media yields substituted 1,3,4-thiadiazoles or 1,2,4-triazoles, respectively.
1,2,4-Thiadiazolylureas. A Postcript to the Oxidative Cyclisation of Thionoamidines

The identity of authentic 5-phenyl-3-ureido-1,2,4-thiadiazole synthesized from the pre-formed heterocycle, and of the product of the oxidative cyclisation of N1-carbamoyl-N3-thiobenzoylguanidine, confirms the structure of 5-substituted-3-ureido-1,2,4-thiadiazoles obtained by either route.
