Procedure

14.1 g (0.04 mole) of 1-(2,2-dicyanethen-1-yl)-2-(2,6-dichloro-4-trifluoromethylthio-phenyl)-hydrazine in 30 ml of ethylene glycol monoethyl ether are heated under reflux for 2 hours. Active charcoal is added to the hot solution, the mixture is filtered and the filtrate is diluted with 60 ml of water. The precipitate which has separated out is filtered off with suction and dried. 9.8 g (70% of theory) of 5-amino-4-cyano-1-(2,6-dichloro-4-trifluoromethylthio-phenyl)-pyrazole of melting point 185° C. to 187° C. are obtained. ##STR119##
