Procedure

(3-{4-[3 -Chloro-4-(3-fluoro-benzyloxy)-phenylamino]-quinazolin-6-yl}-prop-2-ynyl)-carbamic acid tert-butyl ester is prepared by adding prop-2-ynyl-carbamic acid tert-butyl ester (0.978 g, 6.31 mmol), diisopropylamine (1.77 ml, 12.63 mmol), Pd(PPh3)2Cl2 (210 mg, 0.30 mmol) and CuI (57 mg, 0.30 mmol) to a stirred solution of [3-chloro-4-(3-fluoro-benzyloxy)-phenyl]-(6-iodo-quinazolin-4-yl)-amine (3.11 g, 5.74 mmol) in THF (40 ml). After stirring the reaction mixture at rt under N2 for 3 h, the THF is removed under reduced pressured and methylene chloride is added. The organic layer is washed with NH4Cl (sat) and brine, and dried (Na2SO4). The solvent is evaporated and the residual solid is used without further purification.
