Procedure

To 7-methoxy-4-(phenylthio)quinoline (1.38 g, 5.16 mmol) in CH2Cl2(50 mL) at −78° C. was added m-CPBA (77%) (1.25 g, 7.23 mmol) portionwise. The mixture was allowed to slowly warm to RT (3 hrs). The reaction mixture was diluted with CH2Cl2 then neutralized with NaHCO3(sat.). The aqueous phase was extracted three times with CH2Cl2 then the organic layer was dried over Na2SO4, filtered, and concentrated in vacuo. The crude mixture was purified by silica gel chromatography using 0-10% CH2Cl2:MeOH to afford 7-methoxy-4-(phenylsulfinyl)quinoline (1.37 g, 94% yield) as a off-white foam. MH+=284.0.
