Procedure

4-[(4-Fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxy-7-[(2S)-pyrrolidin-2-ylmethoxy)quinazoline (60 mg, 0.14 mmol), (prepared as described for the starting material in Example 12), was dissolved in pyridine (3 ml) and cooled to 0° C. Trichloroacetyl isocyanate (17 μl, 0.14 mmol) was added and the mixture stirred for 2 hours. The solvent was removed under reduced pressure and the residue dissolved in 7N ammonia in methanol and stirred at ambient temperature overnight and then at 50° C. for 2 hours. The solvent was removed under reduced pressure. Column chromatography of the residue (2% to 5% methanol/dichloromethane) gave 7-[(2S)-1-carbamoylpyrrolidin-2-ylmethoxy]-4-[(4-fluoro-2-methyl-1H-indol-5-yl)oxy]-6-methoxyquinazoline (40 mg, 69%) as a yellow solid.
