Procedure

(I4C): Fe powder (2.84 g, 50.9 mmol) was added to a solution of methyl 3-bromo-4-chloro-5-nitrobenzoate (5 g, 16.98 mmol) in AcOH (29.3 ml). The suspension was heated to 60° C. 1 h. The vessel was cooled to rt and then AcOH was removed via rotovap. The residue was placed in a 1 L beaker and was carefully neutralized with saturated sodium bicarbonate. The precipitate was removed via filtration through Celite and the filtrate was extracted with EtOAc. The organics were combined, washed with water and brine, then dried over sodium sulfate. Filtration and concentration afforded methyl 3-amino-5-bromo-4-chlorobenzoate (4.19 g)) as a yellow solid.
