Procedure

A mixture of 3.8 g (16.33 mmol) of 4-chloro-6-nitro-quinoline-3-carbonitrile and 3.7 g (20 mmol) of 3-bromo-4-fluoroaniline in 200 mL of ethanol was refluxed for 3 hr. After the solvent was removed, the residue as dissolved in ethyl acetate and washed with sodium bicarbonate. The product was collected as a pale yellow solid, 6.5 g (71%); ESMS m/z 387.3, 389.2, mp 269-270° C. (dec).
