Procedure

21.2 parts by weight of 2,4,6-trichlorophenylhydrazine and 15.5 parts by weight of methyl ethoxymethylene-2-cyanoacrylate in 120 parts by volume of n-butanol were refluxed for 2 hours. The mixture was cooled, and the precipitate was filtered off with suction to give 22.8 parts by weight of methyl 5-amino-1-(2,4,6-trichlorophenyl)-pyrazole-4-carboxylate of melting point 180°14 181° C.
