Versuchsvorschrift
which is formed in step (1) and which was hitherto unknown, is reacted, in a second stage, either directly in the solution obtained or after intermediate isolation and if appropriate after prior saponification to give free trimethylpyruvic acid (VI), with thiocarbohydrazide (H2N--NH--CS--NH--NH2) in an aqueous solution containing a hydrogen halide acid, at a temperature from about 20° to 100° C. in a manner which is in itself known to give 4-amino-6-tert.-butyl-3-mercapto-1,2,4-triazin-5(4H)-one (VII), and this compound is alkylated in alkaline solution, in a third stage, by means of methyl iodide or methyl bromide or other alkylating agents (especially ethyl iodide or ethyl bromide) in a known manner.
