Tetrahydrofuran → 1-Diallylcarbamoyl-3-propylsulphonyl-1,2,4-triazole

Participants

Reaction Steps

A mixture of 5.25 g. 3-propylsulphonyl-1,2,4-triazole, 5.3 g. diallylcarbamoyl chloride, 25 ml. dry tetrahydrofuran and 6 ml. dry triethylamine was refluxed under anhydrous conditions for 1.5 hours. The reaction mixture was worked up as described in Example 1 to give a solid product which was recrystallized from petroleum ether (b.p. 60° - 80°C.) to give 1-diallylcarbamoyl-3-propylsulphonyl-1,2,4-triazole, m.p. 41° - 42°C. Elemental analysis satisfactory.
