Reaction Steps

300 g of 4-Chloro-but-2-enoic acid [4-(3-chloro-4-fluoro-phenylamino)-7-methoxy-quinazolin-6-yl]-amide and 78 mg azepane were dissolved in 5 ml THF and purged with nitrogen. 0.25 ml DIEA was added and the mixture was stirred at 70° C. for 2 days. The mixture was then diluted with 20 ml ethyl acetate, washed with water and brine and dried over Na2SO4. The resulting solids were flash chromatographed with 0-4% methanol in chloroform. The product was dissolved in CH2Cl2 and treated with excess HCl and ether, then evaporated to dryness to give 115 mg of 4-Azepan-1-yl-but-2-enoic acid [4-(3-chloro-4-fluoro-phenylamino)-7-methoxy-quinazolin-6-yl]-amide (33% yield).
