Reaction Conditions

Reaction Steps

To a solution of 2-fluoro-5-nitrobenzoic acid (5 g, 27.0 mmol) in methanol (135 mL) was added HCl (2.66 mL, 32.4 mmol, 12.2 M), and the mixture was heated with an oil bath at 70° C. for 24 hours. The solvent was evaporated, and the residue was dissolved in ethyl acetate and washed with saturated sodium bicarbonate and brine, dried over sodium sulfate, and concentrated to afford the title compound. 1H NMR (500 MHz, DMSO-d6) δ ppm 8.63 (dd, J=3.0, 6.2, 1H), 8.58-8.50 (m, 1H), 7.74-7.61 (m, 1H), 3.92 (s, 3H).
