Tetrahydrofuran → 1-Dipropylcarbamoyl-3-isopropylsulphinyl-1,2,4-triazole

Participants

Reaction Steps

A mixture of 6.4 g. 3-isopropylsulphinyl-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 1-dipropylcarbamoyl-3-isopropylsulphinyl-1,2,4-triazole as an oily residue which subsequently solidified, m.p. 15° - 20°C. Elemental analysis satisfactory.
