Trifluoroacetic acid → HCID 59398328, compound

Participants

Reaction Steps

To 15 mL of 80% aqueous trifluoroacetic acid solution, 0.44 g of 1-(1,3-dioxolan-2-ylmethyl)-5-methoxyquinolin-2(1H)-one was added, and stirred at room temperature for 5 hours. The solvent was removed under reduced pressure, ethyl acetate and water were added, the organic layer was separated, and sodium chloride was added to the aqueous layer, and extracted twice with ethyl acetate. The organic layer and extracts were combined, washed with aqueous saturated sodium chloride solution, dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to give (5-methoxy-2-oxoquinolin-1(2H)-yl)acetaldehyde as a pale brown solid.
