Procedure

To the liquid mixture of 3-fluoro-4-nitrobenzoic acid 9.71 g and ethanol 35 mL, conc. sulfuric acid 1.6 mL was added, followed by 16 hours' heating under reflux. After distilling the solvent off, water and tert-butyl methyl ether were added to the residue. The organic layer was extracted, washed with water and dried over magnesium sulfate. Distilling the solvent off, 7.40 g of the title compound was obtained.
