Procedure
100 g (406 mmol) of 2-bromo-3-nitrobenzoic acid, 22 g (609 mmol) of conc. HCl and 1 l of methanol are heated under reflux for 24 h. After cooling, the precipitated solid is filtered off with suction, washed with water and ethanol and dried. The residue is recrystallised from ethanol. Yield: 94.6 g (363 mmol), 89.5% of theory.
