Hydrazine hydrate (1:1) → 4-ethoxy-2-fluoroaniline

Participants

Reaction Conditions

Reaction Steps

To a solution of 4-ethoxy-2-fluoro-1-nitro benzene (1.0 g, 5.4 mmol) in absolute EtOH (25 mL) at rt was added 250 mg of Pd/C (Aldrich, 10 wt. % on activated carbon), followed by slow addition of hydrazine hydrate (2.5 mL). The resulting reaction mixture was refluxed at 90° C. for 30 min. It then cooled to rt, filtered through Celite, and then concentrated in vacuo to afford 4-ethoxy-2-fluoro-phenyl amine as a pale yellow oil: MS (ESI) 156 (M+H)+.
