To a solution of 4-fluoro-2-nitrobenzoic acid (22.5 g, 0.1 mol) in ethanol (200 mL), 10% palladium-carbon (1.0 g, 50% hydrate) was added, and the mixture was stirred at room temperature under hydrogen atmosphere for 4 hours. The solution was filtered to remove the catalyst, and the filtrate was concentrated under reduced pressure to give the title compound (8.38 g, 100% yield).
