Versuchsvorschrift

Dipropylcarbamoyl chloride (5.5 g.) was added to a solution of 4.4 g. 3-methylsulphonyl-1,2,4-triazole and 6 ml. dry triethylamine in 25 ml. dry tetrahydrofuran and the resulting mixture refluxed for 2.5 hours under anhydrous conditions. The cooled reaction mixture was filtered to remove triethylamine hydrochloride and the filtrate poured with stirring into 150 ml. ice-cold 0.1N aqueous sodium hydroxide. The precipitated product was collected by filtration, washed with ice-cold water, dried, and crystallized twice from toluene to give 1-dipropylcarbamoyl-3-methylsulphonyl-1,2,4-triazole, m.p. 94°C. Elemental analysis satisfactory.
