Using the same procedure as in Example 26, methyl (2R)-2-[(4-{[1-(3-fluorobenzyl)-1H-indazol-5-yl]amino}quinazolin-5-yl)oxy]propanoate (200 mg, 0.42 mmol) was reacted with ethanolamine (0.15 mL, 2.5 mmol) to give the title compound as a white solid (170 mg, 80%); NMR Spectrum 1.65 (d, 3H), 3.22 (q, 2H), 3.41-3.45 (m, 2H), 4.75 (t, 1H), 5.22 (q, 1H), 5.70 (s, 2H), 7.01-7.12 (m, 4H), 7.36 (dd, 2H), 7.72-7.76 (m, 3H), 8.17 (s, 1H), 8.47 (m, 1H), 8.53 (s, 1H), 8.56 (s, 1H), 10.73 (br s, 1H); Mass spectrum MH+ 501.
