Reaction Steps

To methyl 2-bromo-5-hydroxybenzoate (20 g, 87 mmol) in pyridine (100 mL) was added acetic anhydride (10.2 g, 100 mmol) at 0° C. The mixture was stirred at ambient temperature for 16 hours, concentrated, and ethyl acetate was added. The mixture was washed with saturated NH4Cl(aq) to afford the crude title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 7.79 (d, J=8.7 Hz, 1H), 7.58 (d, J=2.8 Hz, 1H), 7.30 (dd, J=8.7, 2.8 Hz, 1H), 3.86 (s, 3H), and 2.28 (s, 3H).
