Reaction Steps
To a stirred solution of 4-iodo-2-bromobenzoic acid (5 g, 15.29 mmol) in ethyl alcohol (EtOH; 100 mL) was added sulfuric acid (H2SO4; 5 mL), and the reaction mixture was heated at 80° C. for 18 h. The reaction mixture was cooled to 25° C. and concentrated under reduced pressure. The residue was diluted with EtOAc (2×100 mL) and washed with water (100 mL). The combined EtOAc extracts were washed with brine, dried over Na2SO4 and concentrated under reduced pressure to afford the compound as a pale yellow solid (5 g, 92%): 1H NMR (400 MHz, DMSO-d6) δ 8.04 (d, J=1.2 Hz, 1H), 7.71 (d, J=7.6 Hz, 1H), 7.51 (d, J=8.4 Hz, 1H), 4.41 (q, J=7.2 Hz, 2H), 1.41 (t, J=7.2 Hz, 3H).
