실험 절차

5 g of 5-acetyl-8-benzyloxyquinoline are dissolved in 50 ml of chloroform. The solution is ice-cooled and 3.12 g of 80% m-chloroperbenzoic acid are added thereto under stirring. The mixture is stirred at room temperature for 24 hours and at 50° C. for 7.5 hours. The mixture is then stirred at room temperature for 64 hours. 2 g of 80% m-chloroperbenzoic acid are further added to the mixture during the reaction. After the reaction, chloroform is added to the mixture. The mixture is washed with water, a 4% sodium bicarbonate solution and a saturated sodium chloride solution, dried and then evaporated under reduced pressure to remove chloroform. 5-Acetyl-8-benzyloxyquinoline-N-oxide is obtained as yellow solid.
