16.5 parts by weight of 2-chloro-2',6'-dimethyl-N-chloromethyl acetanilide and 9.3 parts by weight of 1,2,4-triazole are refluxed for 8 hours in 60 parts by volume of anhydrous tetrahydrofuran. After the mixture has been cooled, it is filtered, the filtrate is concentrated in vacuo, and the residue is dissolved in 60 parts by volume of chloroform, washed 3 times with water, each time with 40 parts by volume, and dried over sodium sulfate. After evaporation of the solvent in vacuo, there is isolated 21.0 parts by weight of 2-chloro-2',6'-dimethyl-N-(1,2,4-triazol-1-yl-methyl)-acetanilide, m.p.: 115°-118° C.; after recrystallization from ethanol, it melts at 120° C.
