Reaction Steps

2,5-Difluoro-4-nitrobenzoic acid (1 g, 4.9 mmol) was dissolved in ethanol. 10% Palladium on carbon (500 mg) was added and reaction stirred under a hydrogen balloon overnight. The catalyst was filtered off and the filtrate was concentrated under reduced pressure to afford the title compound (0.79 g).
