A solution of 2.97 g (13.6 mmol) of 4-chloro-7-methoxy-3-quinolinecarbonitrile and 4.67 g (27.2 mmol) of 3-bromo aniline in 76 ml of methoxyethanol was refluxed under nitrogen for 5 hours. The solution was cooled and diluted with ether. Solid was collected and washed with ether. The solid was stirred with a hot mixture of ethyl acetate and sodium bicarbonate solution. The organic layer was separated and dried over magnesium sulfate. Solvent was removed and the residue was recrystallized from a chloroform-ethyl acetate mixture giving 1.6 g of 4-[(3-bromophenyl)amino]-7-methoxy-3-quinolinecarbonitrile as a white solid: mass spectrum (electrospray, m/e): M+H 354.1, 356.1.
