99 mg 3-Fluoro-piperidine hydrochloride, 300 mg 4-Chloro-but-2-enoic acid [4-(3-chloro-4-fluoro-phenylamino)-7-methoxy-quinazolin-6-yl]-amide and 0.37 ml of DIEA were dissolved in 5 ml THF stirred at 70° C. overnight. The mixture was then diluted with ethyl acetate, washed with water and brine and dried over Na2SO4. The resulting solids were flash chromatographed with 0-4% methanol in chloroform to give 275 mg of 4-(3-Fluoro-piperidin-1-yl)-but-2-enoic acid [4-(3-chloro-4-fluoro-phenylamino)-7-methoxy-quinazolin-6-yl]-amide.
