Using the same procedure as in Example 26, methyl (2S)-2-[(4-{[1-(3-fluorobenzyl)-1H-indazol-5-yl]amino}quinazolin-5-yl)oxy]propanoate (200 mg, 0.42 mmol) was reacted with methylamine to give the title compound as a white solid (126 mg, 63%) except that the crude material was purified on an HPLC column (C18, 5 microns, 19 mm diameter, 100 mm length) of a preparative HPLC-MS system eluting with a mixture of water and acetonitrile containing 2 g/l of ammonium carbonate (gradient). NMR Spectrum 1.65 (d, 3H), 2.67 (d, 3H), 5.16 (q, 1H), 5.71 (s, 2H), 7.00 (d, 1H), 7.04-7.10 (m, 3H), 7.36 (dd, 2H), 7.71-7.77 (m, 3H), 8.17 (s, 1H), 8.37 (m, 1H), 8.53 (s, 1H), 8.55 (s, 1H), 10.68 (br s, 1H); Mass spectrum MH+ 471.
