Procedure

A mixture of 9.5 g. 3-isobutylsulphonyl-1,2,4-triazole, 8.2 g. dipropylcarbamoyl chloride, 7.5 ml. dry triethylamine and 100 ml. dry tetrahydrofuran was refluxed under anhydrous conditions for 11 hours. The reaction mixture was worked up as described in Example 1, using ether in place of methylene dichloride, to give 1-dipropylcarbamoyl-3-isobutylsulphonyl-1,2,4-triazole, m.p. 62° - 63.5° C. (from petroleum ether, b.p. 62° - 68° C.).
