Versuchsvorschrift

A mixture of 4.1 g. 3-methylsulphonyl-1,2,4-triazole, 4.75 g. diallylcarbamoyl chloride, 20 ml. dry tetrahydrofuran and 5.5 ml. dry triethylamine was refluxed under anhydrous conditions for 1 hour. The reaction mixture was filtered and the filtrate was distilled to dryness under reduced pressure. The solid residue was recrystallized from a mixture of toluene and petroleum ether (b.p. 40° - 60°C.) to give 1-diallylcarbamoyl-3-methylsulphonyl-1,2,4-triazole, m.p. 52° - 54°C. Elemental analysis satisfactory.
