実験手順

A mixture of 2(1H)-Oxo-quinoline-3,4-dicarboxylic acid (2.0 g), phosphorous oxychloride (10 mL) and 8 drops of dimethyl formamide was refluxed with stirring for 20 min. The reaction mixture was concentrated in vacuo and the residue treated with ice water to afford 4-Chloro-furo[3,4-c]quinoline-1,3-dione as a tan solid.
