Versuchsvorschrift

Six parts of 4-chloro-2-fluorophenyl hydrazine hydrochloride was shaken with 100 parts of methylene chloride and 100 parts of 1-molar aqueous sodium hydroxide for one to two minutes until a clear two-phase solution was obtained. The organic phase was washed three times with 60 parts of water, dried with anhydrous magnesium sulfate, and evaporated under a reduced pressure of 50 to 300 mm Hg. to give 3.8 parts of pale tan 4-chloro-2-fluorophenyl hydrazine, m.p. 57°-63° C.
