実験手順

Diethylene glycol monomethyl ether (20 cc) was added to pyrido[3,2-g] quinoline-2,8-dicarboxylic acid (2.01 g, 7.5 mmol) from the above process and cuprous oxide (I) (50 mg, 0.35 mmol), and heated for 5.5 hours at 165° C. Carbon dioxide evolved during the reaction. After the addition of conc. aquous ammonia (25 cc), extracted with dichloromethane (3×100 ml) and dried on potassium carbonate and evaporated dichloromethane to yield pyrido[3,2-g]quinoline.
