    摘要: Method of making 4-amino-6-t-butyl-3-mercapto-1,2,4-triazin-5-one comprising halogenating a 3,3-dimethylbutyric acid with Br.sub.2 or Cl.sub.2 to produce a 2,2-dihalo-3,3-dimethylbutyric acid then reacting the latter with thiocarbohydrazide. Alternatively, a 3,3-dimethylbutyryl chloride can be used as starting material, in which case the halogenation product is contacted with water, an aqueous base, an alcohol, a mercaptan, or an amine to convert it to an acid or salt thereof, anhydride, ester, thioester or amide, and the latter is reacted with thiocarbohydrazide.

    摘要: A process for making 2-aryl-1,2,4-triazine-3,5(2H,4H)-diones which comprises (a) coupling a diazotized arylamine with a lower alkyl cyanoacetate: (b) hydrolyzing and decarboxylating the lower alkyl cyanoglyoxalate arylhydrazone thus produced under alkaline conditions; and (c) cyclizing the resulting glyoxamide arylhydrazone by reaction with a dialkyl carbonate, an alkyl chloroformate or phosgene in the presence of a condensing agent to the corresponding 2-aryl-1,2,4-triazine-3,5(2H,4H)-dione. The products are useful as coccidiostats.
