A solution of 4-chloro-7-{3-[4-(2-fluoroethyl)piperazin-1-yl]propoxy}-6-methoxyquinazoline (240 mg, 0.63 mmol) in DMA (5 ml) was treated with potassium carbonate (96 mg, 0.69 mmol) and 5-hydroxy-2-methylindole (102 mg, 0.69 mmol), (WO 00/47212, Example 48), and stirred at 85° C. for 4 hours. The mixture was cooled and the solvent evaporated under vacuum to give a residue which was purified by column chromatography eluting with methylene chloride/methanol (saturated with ammonia) (92/8). Evaporation of the relevant fractions gave an oil which crystallised on trituration with ether to give 7-{3-[4-(2-fluoroethyl)piperazin-1-yl]propoxy}-6-methoxy-4-[(2-methyl-1H-indol-5-yl)oxy]quinazoline (150 mg, 48%).
