実験手順

(3-{4-[3-Chloro-4-(3-fluoro-benzyloxy)-phenylamino]-quinazolin-6-yl}-allyl)-carbamic acid tert-butyl ester is prepared by adding (3-{4-[3-chloro-4-(3-fluoro-benzyloxy)-phenylamino]-quinazolin-6-yl}-prop-2-ynyl)-carbamic acid tert-butyl ester (3.00 g, 5.63 mmol) to a mixture of Red-Al (5 ml of a 65% wt solution in toluene) in THF (50 ml) at 0° C. under N2. After stirring for 3 h at 0° C., the reaction mixture is quenched by the addition of 10 ml of 10% K2CO3 solution followed by water. The reaction mixture is extracted with ethyl acetate. The organic extracts are dried (Na2SO4), concentrated, and purified by column chromatography (EtOAc:Hex 1:1) to provide 2.01 g (67%) clean desired product.
