Reaction Steps

To a 100 mL flask containing 2-nitro-4-(trifluoromethyl)benzoic acid (940.5 mg, 4 mmol) in 30 mL MeOH was added 100 mg of 10% Pd on charcoal After flushing with hydrogen three times, the reaction mixture was agitated under hydrogen atmosphere for 2 h. The mixture was filtered through a plug of Celite, and the filtrate was concentrated to afford 2-amino-4-(trifluoromethyl)benzoic acid (740 mg, 3.6 mmol, 90%).
