Reaction Steps

To a suspension of 4-(phenylthio)benzoic acid (800 mg, 3.5 mmol) in pyridine (5 mL) and water (5 mL) was added N-phenyl-N,N,N-trimethylammonium tribromide (1.4 g, 3.7 mmol). The mixture was stirred at 20° C. for 12 hours. Then the solvent was evaporated in vacuo to give 4-(phenylsulfinyl)benzoic acid which was used directly without further purification. LRMS (M+H)− m/z: calcd 246.04. found 246.
