Reaktionsschritte

Mixed 122 mg (0.50 mmol) 7-ethoxy-1,4-dihydro-6-methoxy-4-oxo-quinoline-3-carbonitrile and 2.0 ml methylene chloride under N2 and kept temperature near 25° C. Added 218 μl (2.5 mmol) oxalyl chloride and 10 μl (0.125 mmol) DMF. Stirred overnight, diluted with chloroform and stirred in saturated sodium bicarbonate until basic. Separated layers and dried organics with magnesium sulfate, stripped solvent and dried in vacuo, giving 117 mg of tan solid: mass spectrum (electrospray m/e): M+H=262.8, 264.8.
