PCl3 (0.39 mL, 4.45 mmol) was added to an ice-cold solution of 2-{(2-bromophenyl)thio}acetic acid (1.00 g, 4.05 mmol) and 2-chloroaniline (0.47 mL, 4.45 mmol) in pyridine (15 mL). The reaction mixture was stirred at room temperature for 30 min. Water (few drops) was added and the mixture was concentrated under reduced pressure. The residue was purified by flash chromatography (CH2Cl2) to give the title compound (957 mg, 66% yield) as a yellow solid.
