A mixture of 3-iodobenzamide (4.28 g, 17.3 mmol), water (25.00 g, 1387.7 mmol), triethylamine (8.00 g, 79.1 mmol), palladium(II) acetate (0.28 g, 1.2 mmol), and bis(diphenylphosphino)propane (0.52 g, 1.3 mmol) in acetonitrile (50 mL) was pressurized to 40 psi with carbon monoxide and the pressure was released. After six such cycles, the bottle was pressurized again and the contents were stirred at 85° C. for 3 h. The reaction mixture was cooled to room temperature and depressurized. The solvent was evaporated and ethyl acetate (200 mL) was added. The solution was filtered and then extracted with water (2×200 mL). The combined aqueous layers were acidified with 12 M HCl to pH 0. The solid was filtered off and air-dried to give 3-carboxybenzamide (1.93 g, 87%) as a yellow solid
