Tetrahydrofuran → HCID 20354946, compound

Participants

Reaction Steps

A mixture of 10.2 g. 3-pentylsulphonyl-1,2,4-triazole, 8.2 g. diallylcarbamoyl chloride, 75 ml. dry tetrahydrofuran and 7.5 ml. dry triethylamine was refluxed under anhydrous conditions for 1.5 hours. The reaction mixture was worked up as described in Example 1, using ether in place of methylene dichloride. An oily residue was obtained which was distilled under reduced pressure to give a product, b.p. 193° - 194° C./0.25 mm., which solidified on cooling. This product was recrystallized from petroleum ether (b.p. 60° - 80° C.) to give 1-diallylcarbamoyl-3-n-pentylsulphonyl-1,2,4-triazole, m.p. 28° - 30° C. Elemental analysis satisfactory.
