Procedure

Analogously to instructions given by A. Dornow and others (Chem. Berichte 97 (1964), page 2173-2178), 53 g (0.5 mole) of thiocarbohydrazide are dissolved in 500 ml of boiling water and 65 g (0.5 mole) of trimethylpyruvic acid are added slowly. A colorless precipitate is deposited, which is filtered off, washed with water and dried in vacuo at 50° C. 6-tert.-butyl-3-mercapto-4-amino-1,2,4-triazin-5(4H)-one is obtained from this reaction in almost quantitative yield.
