Reaction Steps

10.5 g (0.05 mol) of 3-chloro-4-trifluoromethylphenylhydrazine were dissolved in 50 ml of toluene. 4.9 g of maleic anhydride (0.05 mol) in the solid form were introduced into this solution at room temperature. This caused the temperature to rise by a few degrees, while the reaction product precipitated in the crystalline form. The mixture was then heated to about 50° C. for some time, after which it was allowed to cool and the product was filtered off. 10 g (65% of theory) of maleic acid mono-(3-chloro-4-trifluoromethyl-phenyl)-hydrazide of melting point 180°-182° C. were obtained.
