실험 절차

A mixture of 4.35 g. 3-ethylsulphinyl-1,2,4-triazole, 6.0 ml. diallylcarbamoyl chloride, 25 ml. dry tetrahydrofuran and 7.5 ml. dry triethylamine was refluxed under anhydrous conditions for 2 hours. The reaction mixture was filtered and the filtrate distilled under reduced pressure to remove solvent, giving a residual oil which solidified on cooling. This solid product was recrystallized from petroleum ether (b.p. 60° - 80° C.) to give 1-diallylcarbamoyl-3-ethylsulphinyl-1,2,4-triazole, m.p. 41° - 43° C. Elemental analysis satisfactory.
