A solution of 5.2 g (19.7 mmol) of 4-chloro-7-methoxy-6-nitro-3-quinolinecarbonitrile and 3.7 g (21.7 mmol) of 3-bromo aniline in 130 ml of methoxyethanol was refluxed under nitrogen for 4 hours. The reaction mixture was poured into dilute sodium bicarbonate solution. Solid was collected and washed with water and dried in air. The solid was chromatographed on silica gel eluting with chloroform-ethyl acetate 9:1. Solvent was removed from product fractions giving 1.2 g of 4-[(3-bromophenyl)amino]-7-methoxy-6-nitro-3-quinolinecarbonitrile as a yellow solid: mass spectrum (electrospray, m/e): M+H 399.0, 402.0.
