Reaction Conditions

Reaction Steps

A mixture of 4-chloro-6-methoxy-7-(3-(pyrrolidin-1-yl)propoxy)quinazoline (218 mg, 0.68 mmol), (prepared as described for the starting material in Example 9), potassium carbonate (138 mg, 1.13 mmol) and 3-fluoro-7-hydroxyquinoline (117 mg, 0.72 mmol), (prepared as described for the starting material in Example 157), in DMF (4.5 ml) was stirred at 100° C. for 4 hours and then allowed to cool to ambient temperature. The reaction mixture was evaporated to dryness and the residue taken up in dichloromethane, washed with water, brine and dried (MgSO4). The organic fractions were evaporated to dryness and the residue recrystallised from acetonitrile to give 4-(3-fluoro-quinolin-7-yloxy)-6-methoxy-7-(3-(pyrrolidin-1-yl)propoxy)quinazoline (86 mg, 28%).
