Procedure

A mixture of 4-Chloro-furo[3,4-c]quinolin-3(1H)-one (500 mg), 10% Palladium on carbon (100 mg) and sodium acetate (500 mg) in 20 mL of acetic acid was hydrogenated at atmospheric pressure for 2 h. After filtration through celite, the solvent was removed in vacuo, and the residue was taken up in methylene chloride. After filtration the solvent was removed in vacuo to afford Furo[3,4-c]quinolin-3(1H)-one as a solid.
