Reaction Steps

A solution of ethyl 2-(2-bromo-4-fluoro-5-nitrophenyl)acetate (2.127 g, 6.95 mmol) in EtOH (70 mL) was treated with iron powder (3.88 g, 69.5 mmol) and satd ammonium chloride (14.48 mL, 69.5 mmol) and heated to 55° C. for 1 h. The mixture was cooled to RT, filtered through a pad of diatomaceous earth, rinsed well with EtOH and the organics concentrated under reduced pressure. The resulting aqueous residue was treated with satd. NaHCO3, extracted with EtOAc (2×) and the combined organics were washed with water, dried (MgSO4), and concentrated to afford ethyl 2-(5-amino-2-bromo-4-fluorophenyl)acetate (1.792 g, 93% yield) as an amber oil. 1H NMR (400 MHz, DMSO-d6): δ 7.25 (d, 1H), 6.76 (d, 1H), 5.35 (s, 2H), 4.08 (q, 2H), 3.61 (s, 2H), 1.18 (t, 3H); MS (ESI) m/z: 278.0 [M+H]+.
