Abstract
A process for preparing the compound 5-t-butyl-2-methylamino-1,3,4-thiadiazole, ##STR1## in high yield by the reaction of 4-methyl-3-thiosemicarbazide with pivalic acid in a solution containing both polyphosphoric acid and concentrated sulfuric acid, followed by neutralizing the reaction mixture with a neutralizing mixture comprising an organic solvent and an alkaline substance dissolved in water and separating 5-t-butyl-2-methylamino-1,3,4-thiadiazole from the organic phase.
