In a 100 mL round bottom flask, 6-chloro-7-methoxyquinoline was dissolved in DCM (25.8 mL) and MTO (0.051 g, 0.207 mmol) was added. The reaction mixture was capped and vented with a needle, then placed in an ice bath to cool. Once cool, hydrogen peroxide (0.633 mL, 10.33 mmol) was added drop-wise. When the addition was complete, the reaction mixture was removed from cooling, warmed to room temperature and stirred overnight (18 h). MnO2 (10 mg, 0.115 mmol) was added and the reaction mixture was stirred for an additional 2 h. The reaction mixture was filtered through celite, washing with DCM, then concentrated in vacuo to yield 6-chloro-7-methyoxyquinoline 1-oxide (1.036 g) MS [M+H+]=210.3.
