Reaction Steps

A solution of 4-fluoro-3-nitrobenzoic acid (Alfa Aesar, 10.0 g, 54 mmol) and concentrated H2SO4 (0.2 ml, 4.1 mmol) in EtOH (200 ml) was refluxed for 40 h. The mixture was cooled to 0° C., solid NaHCO3 and MgSO4 was added, and the suspension was filtered and concentrated in vacuo. The residue was purified by chromatography on silica gel (0→30% EtOAc-hexanes) to yield the title compound as an off-white solid.
