الإجراء التجريبي

Into 3 mL of a 90% aqueous trifluoroacetic acid solution, 361 mg of 1-(1,3-dioxolan-2-ylmethyl)-3-methylquinolin-2(1H)-one was dissolved, and the mixture was stirred at room temperature overnight. The solvent was removed under reduced pressure, and the reaction mixture was alkalified with an aqueous saturated sodium hydrogen carbonate solution, and then extracted with ethyl acetate. The organic layer was washed sequentially with water and an aqueous saturated sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to obtain 354 mg of a pale yellow oily substance, (3-methyl-2-oxoquinolin-1(2H)-yl)acetaldehyde.
