Analogously to Example 1, N-cyclohexyl-bis-(chloro-carbonyl)-amine (prepared analogously to Snythesis 1970, pages 542-543; boiling point 80°-82° C/0.3 mm Hg) and acetone-S-methylisothiosemicarbazone hydroiodide, with addition of triethylamine, yielded 1-cyclohexyl-3-isopropylideneamino-4-methylmercaptotetrahydro- 1,3,5-triazine-2,6-dione as a pale yellow powder of melting point 111°-112° C.
