Reaction Steps

A mixture of 5-nitro-2-trifluoromethoxybenzoic acid (6.43 g, 25.6 mmol) and 128 mg of 10% Pd/C in 10 mL of absolute ethanol was stirred in a hydrogen atmosphere overnight at room temperature. The catalyst was filtered off and the filtrate was evaporated to dryness. The re-residue was triturated with diethyl ether and the crystals were filtered off and dried to afford 1.644 g (29%) of 5-amino-2-trifluoromethoxybenzoic acid.
