Reaction Steps

Add Na2SO4(8.5 mmol) to a solution of 4-Bromo-3-nitro-benzoic acid methyl ester (1.2 mmol) in EtOH (40 mL). Heat the reaction at 70° C. for 30 min and then at room temperature overnight. Add a saturated solution of NaHCO3(pH=11-12) and extract with EtOAc (2×50 mL). Dry over NaSO4, filter and evaporate to dryness to provide 4-Bromo-3-amino-benzoic acid methyl ester.
