Reaction Steps

A mixture of 4-fluoro-3-nitrobenzoic acid (10.0 g; 54.0 mmol), SOCl2 (20.0 mL; 270 mmol) and DMF (2-3 drops) was refluxed for 4 h, concentrated and the residue was dissolved in DCM (25 mL) and slowly added to a mixture of 4-bromoaniline (9.3 g; 54.1 mmol) and TEA (11.4 mL; 81.0 mmol) in DCM (50 mL) at 0° C. The mixture was stirred for 1 h at rt, concentrated, EtOAc was added and the organic phase was washed with aqueous NaHCO3, aqueous HCl (1 M), dried over Na2SO4, filtered and concentrated to give the sub-title compound. Yield: 18.0 g (98%).
