Reaction Steps

2-Fluoro-5-nitrobenzoic acid (1.85 g) was dissolved in ethanol (30 ml). Concentrated sulfuric acid (1.0 ml) was added to the solution, and the mixture was stirred at 65° C. overnight. The solvent was removed from the reaction solution by distillation under the reduced pressure, and the residue was adjusted to pH 7 by the addition of a saturated aqueous sodium hydrogencarbonate solution, followed by extraction with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was then removed by distillation under the reduced pressure to give 1.79 g (84.3%) of ethyl 2-fluoro-5-nitrobenzoate.
