実験手順
Sodium hydride (60% in oil) (1.3 g) was added at 0° C. to a DMF solution (50 ml) of 2-oxo-1,2-dihydroquinoline-3-carboxaldehyde (5.13 g), followed by stirring for 30 minutes. 4-chlorobenzyl bromide (7.0 g) was added, and the resulting mixture was stirred at room temperature overnight. Water was added to the reaction mixture, extraction with ethyl acetate was performed, and the extract was dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:n-hexane=1:10→1:4). The purified product was recrystallized from a chloroform-diisopropyl ether mixed solvent to thereby obtain 6.57 g (yield: 72%) of 1-(4-chlorobenzyl)-2-oxo-1,2-dihydroquinoline-3-carboxaldehyde as a white powder.
