15.1 g (0.1 mol) of the potassium salt of 2-cyano-2-oximinoacetamide and 28.3 g (0.106 mol) of 1-(2-(p-toluenesulphonyloxy)-ethyl)-1,2,4-triazole in 100 ml of acetonitrile are heated at 80° C. for 10 hours. The solid product is separated off, and the acetonitrile solution is evaporated down in vacuo. The residue is recrystallized from boiling diethyl ketone. 13.4 g of 2-cyano-2-[2-(1,2,4-triazol-1-yl)-ethyl-oximino]-acetamide of melting point 137° C. are obtained: this is 64% of theory.
