実験手順

A mixture of 6.4 g. 3-isopropylsulphinyl-1,2,4-triazole, 8.0 ml. diallylcarbamoyl chloride, 25 ml. dry tetrahydrofuran and 10 ml. dry triethylamine was refluxed under anhydrous conditions for 2 hours. The cooled reaction mixture was filtered and the filtrate was distilled under reduced pressure to give an oily residue which subsequently solidified. This solid residue was recrystallized from petroleum ether (b.p. 60° - 80° C.) to give 1-diallylcarbamoyl-3-isopropylsulphinyl-1,2,4-triazole, m.p. 32° - 34° C. Elemental analysis satisfactory.
