실험 절차
A mixture of 2(1H)-Oxo-quinoline-3,4-dicarboxylic acid (2 g), phosphorous oxychloride (4 g) and dry chloroform (30 mL) was heated at reflux for 2 h. The solvent and excess reagents are removed in vacuo and the residue was treated with ice water to afford Furo[3,4-c]quinoline-1,3,4(5H)-trione as a yellow solid.
