Procedure
[3-({5-{[1-(2-tert-butoxyethyl)piperidin-4-yl]oxy}-7-[3-(4-methylpiperazin-1-yl)propoxy]quinazolin-4-yl}amino)-1H-pyrazol-5-yl]acetic acid (140 mg, 0.22 mmol) in dimethylformamide (1 ml) was reacted with 3-fluoroaniline (24 μl, 0.25 mmol) in the presence of 1-(3-dimethylamino-propyl)-3-ethylcarbodiimide hydrochloride (48 mg, 0.25 mmol) and 2-hydroxypyridin-1-oxide (27 mg, 0.24 mmol) at 50° C. for 45 minutes. The solvent was evaporated and the residue purified by chromatography on silica gel. Elution with dichloromethane:methanol (97:3) then dichloromethane:methanolic ammonia (95:5) yielded 2-[3-({5-{[1-(2-tert-butoxyethyl)piperidin-4-yl]oxy}-7-[3-(4-methylpiperazin-1-yl)propoxy]quinazolin-4-yl}amino)-1H-pyrazol-5-yl]-N-(3-fluorophenyl)acetamide (109 mg, 58% yield):
