Reaction Steps
Following essentially the same procedure as in example 2, but using an equivalent amount of 5-chloro-2-(3-trifluoromethylphenyl)-pyridazin-3(2H)-one and acetone hydrazone in place of the 4,5-dichloro-2-(3-trifluoromethylphenyl)-pyridazin-3(2H)-one and methylhydrazine used therein, there is obtained 2-(3-trifluoromethylphenyl)-5-(2-isopropylidenehydrazino)-pyridazin-3(2H)-one, (m.p. 255° to 257° C).
