実験手順

A mixture of 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (350 mg, 1.0 mmol), (prepared as described for the starting material in Example 24), 3-(2-chloroethoxy)pyridine hydrochloride (234 mg, 1.2 mmol) and potassium carbonate (456 mg, 3.3 mmol) in NMP (20 ml) was heated at 90° C. for 2 hours. The mixture was allowed to cool, diluted with water and extracted with ethyl acetate. The combined extracts were washed with water, dried (MgSO4) and the solvent removed by evaporation. The residue was purified by column chromatography eluting with methylene chloride/methanol mixtures (100/0 increasing to 95/5) to give 4-(4-chloro-2-fluoroanilino)-6-methoxy-7-(2-(3-pyridyloxy)ethoxy)quinazoline (95 mg, 20%). m.p. 188-190° C. 1H NMR Spectrum: (DMSOd6) 3.90(s, 3H); 4.45(m, 4H); 7.24(s, 1H); 7.18(dd, 1H); 7.2-7.60(m, 3H); 7.80(s, 1H); 8.20(d, 1H); 8.35(s, 2H); 9.50(s, 1H) MS-ESI: 441 [MH]+
