To 25 mL of a chloroform solution containing 1.72 g of 4-methoxyquinoline, 3.16 g of m-chloroperbenzoic acid was added, and the mixture was stirred at room temperature for 12 hours. The reaction mixture was added with 20 mL of an aqueous saturated sodium hydrogen carbonate solution. The organic layer was separated, and the aqueous layer was extracted with chloroform. The organic layer and the extract were combined, the resultant solution was washed with an aqueous saturated sodium chloride solution, and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to obtain a light brown oily substance, 4-methoxyquinoline N-oxide.
