A mixture of 6.9 g. 3-n-butylsulphinyl-1,2,4-triazole, 8.0 ml. dipropylcarbamoyl 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 distilled under reduced pressure to give an oily residue which subsequently solidified. This solid product was recrystallized from petroleum ether to give 1-dipropylcarbamoyl-3-n-butylsulphinyl-1,2,4-triazole, m.p. 39° - 40°C. Elemental analysis satisfactory.
