FIELD: heterocyclic compounds. SUBSTANCE: pyruvic acid reacts at 35-40 C with sulfuryl chloride in the presence of ethylene glycol ether (preferable is dimethyl ether or dioxane). Thioformamide is added into thus prepared chloropyruvic acid in the medium of ethylene glycol ether (temperature 60-65 C being preferable). EFFECT: intensifies the process, decreases reaction time.
