(4-Fluorophenyl)hydrazine → HCID 178469981, compound

Participants

Reaction Steps

To ethanol (30 ml) were added 4-fluorophenylhydrazine (7.75 g) and ethyl ethoxymethylenemalonate (2.5 g), and the mixture was refluxed for 3 h. The solvent was evaporated under reduced pressure and diisopropyl ether was added to the residue to allow crystallization. The crystals were recrystallized from a mixed solvent of ethyl acetate-diisopropyl ether to give the title compound (2.5 g), melting point: 127–128° C.
