실험 절차

19 g (0.075 mole) of 2,6-dichloro-4-trifluoromethyl-phenylhydrazine and 16 g (0.075 mole) of 3-dimethylamino-2-(1,2,4-triazol-1-yl)-acrylonitrile hydrochloride in 200 ml of ethanol are heated at 75° C. to 78° C. for 5 hours, with stirring. For working up, the solvent is distilled off and the residue is triturated with water and dried over clay. 26 g (96% of theory) of 5-amino-1-(2,6-dichloro-4-trifluoromethylphenyl)-4-(1,2,4-triazol-1-yl)-pyrazole of melting point 170°-174° C. are obtained.
