Procedure

22 mg of methyl 1-(1,3-dioxolan-2-ylmethyl)-1,2-dihydro-2-oxoquinoline-5-carboxylate was dissolved in 2 mL of 50% aqueous trifluoroacetic acid solution, and stirred at room temperature for 11.5 hours. After the reaction mixture was alkalized by adding aqueous saturated sodium hydrogen carbonate solution, it was extracted with ethyl acetate. The organic layer was washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give methyl 2-oxo-1-(2-oxoethyl)-1,2-dihydroquinoline-5-carboxylate as a colorless oil.
