A mixture of 6.45 g. 3-ethylsulphonyl-1,2,4-triazole, 5.9 g. N-allyl-N-ethylcarbamoyl chloride, 6.5 ml. dry triethylamine and 80 ml. dry tetrahydrofuran was refluxed under anhydrous conditions for 6 hours. The reaction mixture was worked up as described in Example 1 to produce a solid residue which was recrystallized from benzene/petroleum ether, b.p. 40° - 60°C. to give 1-(N-allyl-N-ethylcarbamoyl)-3-ethylsulphonyl-1,2,4-triazole, m.p. 41° - 43°C.
