To 70 mg of 1-(1,3-dioxolan-2-ylmethyl)-7-(1H-imidazol-1-yl)-4-methylquinolin-2(1H)-one, 2 mL of 80% aqueous trifluoroacetic acid solution, was added, and stirred at room temperature for 1 hour, thereafter allowed to stand at room temperature for 14 hours. Ethyl acetate was added, neutralized with aqueous saturated sodium hydrogen carbonate solution, ethyl acetate was added, the organic layer was separated, and the aqueous layer was extracted 3 times with ethyl acetate. The organic layer and extracts were combined, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give (7-(1H-imidazol-1-yl)-4-methyl-2-oxo-1,2-dihydroquinolin-1-yl)acetaldehyde as a white solid.
