Reaction Steps

To 3 mL of a xylene solution containing 50 mg of 1-(1,3-dioxolan-2-ylmethyl)-7-methoxy-4-methylquinolin-2(1H)-one, 20 mg of serene dioxide was added, and the mixture was stirred for 6 hours under reflux. The reaction mixture was cooled to 60° C., the insoluble material filtered off, and the filtration residue was washed with chloroform. The filtrate and the washing solution were combined, and the solvent was removed under reduced pressure. The residue thus obtained was added with diethyl ether, and a solid substance was collected by filtration to obtain a yellow solid, 34 mg of 1-(1,3-dioxolan-2-ylmethyl)-7-methoxy-2-oxo-1,2-dihydroquinoline-4-carbaldehyde.
