To a solution of 5-methoxy-2-nitrobenzamide (9.70 g, 49.4 mmol) in methanol (250 mL) was added 10% palladium carbon (2.00 g), and the mixture was stirred under hydrogen atmosphere (1 atm) at room temperature for 6 hr. The insoluble material was filtered off, and the filtrate was concentrated to give 2-amino-5-methoxybenzamide as a pale-yellow powder (8.20 g, 99%).
