m-Chloroperbenzoic acid → HCID 59427334, compound

Participants

Reaction Steps

To a mixture of 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) and the mixture was allowed to slowly warm to RT (ca. 1 h). The mixture was diluted with CH2Cl2 and washed with saturated NaHCO3. The organic layer was dried over Na2SO4, filtered and concentrated under reduced pressure. The crude mixture was purified by silica gel chromatography using CH2Cl2:MeOH 100:0 to 90:10 to afford 7-methoxy-4-(phenylsulfinyl)quinoline as a off-white solid. MS found: M+H+=284.0.
