Procedure
Using an analogous procedure to that described for the preparation of Example 14, 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxy-7-(3-piperazin-1-ylpropoxy)quinazoline (250 mg, 0.54 mmol) was reacted with 2,2,2-trifluoroethyl trifluoromethanesulphonate (128 mg, 0.59 mmol) and purified by column chromatography, eluting with 5% methanol/methylene chloride to give a sticky solid. The sticky solid was dissolved in methanol and absorbed onto an Isolute SCX column. The column was washed with methanol and eluted with 7N ammonia in methanol. The product was triturated in ether/isohexane and filtered to give 4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxy-7-{3-[4-(2,2,2-trifluoroethyl)piperazin-1-yl]propoxy}quinazoline (130 mg, 44%).
