Procedure

106.8 g (0.44 mol) of 1-(2,4-dichlorophenyl)-2-(1,2,4-triazol-1-yl)-1-ethanone are dissolved in 780 ml of ethanol, 48 g of hydroxylammonium nydrochloride are added and the mixture is heated under reflux for five hours. Thereafter, 1000 ml of water are added and the reaction mixture is filtered. 51 g (45% of theory) of 1-(2,4-dichlorophenyl)-1-oximino-2-(1,2,4-triazol-1-yl)-ethane of melting point 165°-170° C. are obtained. ##STR15##
