8-Methylquinoline → Quinoline, 8-methyl-, 1-oxide

Participants

Reaction Steps

To a solution of 8-methylquinoline (1.00 g, 6.98 mmol) in DCM (21 ml) was added 3-chlorobenzoperoxoic acid (2.35 g, 10.5 mmol), and the reaction was stirred for 16 hours at ambient temperature. The reaction was diluted with EtOAc and washed with 20% sodium sulfite, saturated sodium bicarbonate, and saturated sodium chloride. The organic layer was dried over anhydrous sodium sulfate, filtered, and concentrated. The residue was purified on the silica gel eluting with a gradient of 1-10% MeOH/DCM to yield the desired compound (0.440 g, 2.76 mmol, 39.6% yield).
