The 4-chloro-5,7-difluoro-2-(5-fluoro-2-(methylthio)phenyl)-3-methylquinoline (320 mg, 0.90 mmol) was dissolved in a mixture of THF (6.7 mL) and water (2.2 mL). To the solution was added Oxone™ (1.40 g, 2.2 mmol) and the resulting slurry was stirred vigorously for 16 h. The reaction mixture was added to 25 mL of water and stirred vigorously for 10 min and then filtered. The precipitate was dissolved in EtOAc and then dried over magnesium sulfate. The filtrate was cond to give 4-chloro-5,7-difluoro-2-(5-fluoro-2-(methylsulfonyl)phenyl)-3-methylquinoline. Mass Spectrum (ESI) m/e=386.0 (M+1).
