Conditions

Temperature
50 °C

Procedure

A solution of 5-amino-6-nitroquinoline (3 g, 16 mmol) in 50 mL dimethylformamide was treated with triethylamine (3.2 g, 32 mmol) and ethyloxalyl chloride (3.2 g, 24 mmol) and heated at 50° C. for 1 hour. After removing the triethylamine hydrochloride by filtration, the filtrate was concentrated and diethyl ether added. The title compound (3.7 g, 80% yield) was collected by filtration.
