A mixture of 4-chloro-6-methoxy-7-(3-piperidinopropoxy)quinazoline (144 mg, 0.43 mmol), (prepared as described for the starting material in Example 67), potassium carbonate (91 mg, 0.66 mmol) and 3-fluoro-7-hydroxyquinoline (77 mg, 0.47 mmol), (prepared as described for the starting material in Example 157), in DMF (3 ml) was stirred at 100° C. for 2 hours and then allowed to cool to ambient temperature. The reaction mixture was evaporated to dryness and the residue chromatographed on silica eluting with methanol/dichloromethane/aqueous ammonia (0.880) (5/100/1). The relevant fractions were combined and evaporated to dryness to give 4-(3-fluoro-quinolin-7-yloxy)-6-methoxy-7-(3-piperidinopropoxy)quinazoline (87 mg, 44%).
