Procedure
SOCl2 (33.7 g, 0.283 mol) was added dropwise to a solution of 3-bromo-4-fluoro-5-nitro-benzoic acid (37.4 g, 0.142 mol) in EtOH (300 mL). The reaction mixture was refluxed overnight, cooled to RT and subsequently concentrated under reduced pressure. The residue was dissolved in EtOAc (300 mL), washed twice with water (50 mL), dried (Na2SO4) and concentrated to give the title compound as yellow solid. 1H-NMR (300 MHz, CDCl3): δ (ppm) 8.65 (m, 1H), 8.53 (m, 1H), 4.46 (m, 2H), 1.45 (m, 3H).
