実験手順

A mixture of 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (300 mg, 0.94 mmol), (prepared as described for the starting material in Example 15), 4-(2-chloroethoxy)pyridine hydrochloride (155 mg, 0.79 mmol) and potassium carbonate (260 mg, 1.9 mmol) in NMP (20 ml) was heated at 90° C. for 2 hours, allowed to cool to ambient temperature and stirred for a further 18 hours. The mixture was diluted with water and extracted with ethyl acetate. The extract was 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-(4-pyridyloxy)ethoxy)quinazoline (20 mg, 7%).
