Procedure

To a solution of 3-benzylsulfonyl-1,2,4-triazole, 4.8 g (0.022 m) in 25 ml dry pyridine, 3.3 g (0.024 m) diethylcarbamoyl chloride is added dropwise. Let it stir overnight and pour into ~100 ml cold dilute hydrochloric acid. The product is extracted with ethyl acetate. Dry the organic layer and evaporate to give the desired product. Recrystallize from toluene-hexane to give white crystals, 5.8 g (81%) m.p. 87°-88° C.
