Procedure

A solution of 4.1 g. 3-(2-ethoxyethylsulphonyl)-1,2,4-triazole, 3.5 g. diallylcarbamoyl chloride and 4 ml. triethylamine in 40 ml. dry tetrahydrofuran was refluxed under anhydrous conditions for 15 hours. The cooled reaction mixture was filtered to remove triethylamine hydrochloride and the filtrate was evaporated to remove solvent. The residue was triturated with petroleum ether (b.p. 40°-60° C.) to give a solid product. This product was collected and recrystallised from ether/petroleum ether b.p. 40°-60° C. to give 1-diallylcarbamoyl-3-(2-ethoxyethylsulphonyl)-1,2,4-triazole, m.p. 62°-63° C. Elemental analysis satisfactory.
