Reaction Steps

A mixture of 200 mg of 4-[(3-chloro-4-fluoro-phenyl)amino]-6-{[4-(piperazin-1-yl)-1-oxo-2-buten-1-yl]amino}-7-cyclopropylmethoxy-quinazoline and 0.11 ml of ethyl acrylate in 2 ml of ethanol is heated under reflux for one hour. The solvent is evaporated in vacuo and the crude product is purified by column chromatography on silica gel with methylene chloride/methanol (95:5 to 90:10) followed by recrystallization from diethyl ether. Yield: 164 mg (69% of theory), Melting point: 183-185° C. Mass spectrum (ESI−): m/z=609, 611 [M−H]−
