Reaction Steps
4-bromo-but-2-enoic acid[4-(3-chloro-4-fluoro-phenylamino)-3-cyano-7-methoxy-quinolin-6-yl]-amide (250 mg, 0.51 mmol.) and 2-(methylamino)-ethanol(97 mg, 1.02 mmol.) were dissolved with stirring, under nitrogen, in 9 ml anhydrous dimethylformamide. After 48 hours, the mixture was partitioned between saturated sodium bicarbonate solution, and ethyl acetate. The organic phase was seperated, dried over magnesium sulfate, filtered, and evaporated to give a gum. It was chromatographed on silica gel, and eluted with 40/4/1 (ethyl acetate/methanol/triethylamine) producing 183 mg (74%) of the purified product as a yellow solid: mp 210-214° C.
