反応手順
43.9 parts by weight of 2-chloro-2',6'-dimethyl-N-chloromethyl acetanilide and 25.8 parts by weight of pyrazole are stirred for 7 hours at 90° C. in 120 parts by volume of toluene. After the mixture has cooled it is filtered, and the filtrate is washed 3 times with water, each time with 50 parts by volume, and dried over sodium sulfate. The solvent is evaporated and the residue pasted with 50 parts by volume of petroleum ether to give 39.1 parts by weight of 2-chloro-2',6'-dimethyl-N-(pyrazol-1-yl-methyl)-acetanilide, m.p.: 81° C.
