4-fluoro-2-chloro-benzoic acid (10 g) was combined with sodium methoxide (393 mL, 4.37 M in methanol) and heated at 75 C for 46 h. The reaction was cooled to room temp and acidified with 1 N HCl. The mixture was extracted with EtOAc (3×). The combined extracts were then dried (MgSO4) and concentrated to give 8.5 g of 4-methoxy-2-chloro-benzoic acid as a white solid.
