To a mixture of 4-amino-3-nitro-benzoic acid (10.0 g, 54.9 mm0l) suspended in methanol (150 mL) was added thionyl chloride (3.99 mL, 54.9 mmol). The mixture was heated to reflux overnight, then cooled to room temperature and filtered. The solid recovered by filtration was rinsed with cold methanol and dried to give 8.68 g (81%) of 4-amino-3-nitro-benzoic acid methyl ester.
