Morpholine → N-[4-(3-bromoanilino)-3-cyano-7-methoxyquinolin-6-yl]-4-morpholin-4-ylbut-2-enamide

To a mixture of 0.69 g (1.87 mmol) of 4-[(3-bromophenyl)amino]-7-methoxy-6-amino-3-quinolinecarbonitrile and 0.98 ml (5.6 mmol) of Hunig's base in 50 ml of dry THF at 0° C., with stirring, was added a THF solution containing 0.86 g (5 mmol) of 4-bromocrotonyl chloride dropwise. The mixture was stirred for a additional 0.5 hour and then was added to a solution of 4.89 ml (56 mmol) morpholine in 50 ml THF at 0° C. dropwise. The solution was stirred an additional 0.5 hour and then the mixture was poured into diluted sodium bicarbonate solution . The organic layer was separated and dried over sodium sulfate. The residue was chromatographed to give 0.38 g of grey solid: mass spectrum (electrospray, m/e): M+H 521.9 and 523.8.
