A mixture of 6.45 g. 3-ethylsulphonyl-1,2,4-triazole, 6.6 g. diallylcarbamoyl chloride, 25 ml. dry tetrahydrofuran and 8 ml. dry triethylamine was refluxed under anhydrous conditions for 1.5 hours. The cooled reaction mixture was filtered and the filtrate distilled under reduced pressure to remove solvent and give a product which distilled at 187° C./0.2 mm. This product solidified and was recrystallized from petroleum ether (b.p. 60° - 80° C.) to give 1-diallylcarbamoyl-3-ethylsulphonyl-1,2,4-triazole, m.p. 39° - 42° C. Elemental analysis satisfactory.
