Reaction Steps

4-Bromo-3-fluoroaniline (0.570 g, 3.00 mmol) and phosphorus trichloride (0.176 ml, 2.0 mmol) were added to a solution of 5-chlorosalicylic acid (0.690 g, 4.00 mmol) in toluene (30 ml), and the mixture was refluxed for 2 hours. Saturated aqueous sodium hydrogencarbonate was added to the reaction mixture, and the mixture was concentrated under reduced pressure and extracted with tetrahydrofuran. The organic layer was washed with saturated aqueous sodium hydrogencarbonate and dried over anhydrous sodium sulfate. The solvent was evaporated under reduced pressure to give the title compound (0.930 g, 90%) as a white solid.
