The procedure described in Example 25 was repeated using (3R,5S)-5-[({4-[3-chloro-4-fluoroanilino]-7-methoxyquinazolin-5-yl}oxy)methyl]pyrrolidin-3-ol (209 mg) with methoxyacetic acid (42 μl) to give the title compound as a white solid in 91% yield; NMR spectrum (DMSO-d6) 9.96 (s, 1H), 8.45 (s, 1H), 8.17-8.14 (m, 1H), 7.76-7.72 (m, 1H), 7.45 (t, 1H), 6.83 (s, 2H), 5.10 (m, 1H), 4.73-4.69 (m, 1H), 4.47-4.38 (m, 2H), 4.25 (dd, 1H), 4.10-3.98 (m, 2H), 3.94 (s, 3H), 3.51 (dd, 1H), 3.40 (s, 1H), 3.29 (s, 3H), 2.05-2.02 (m, 2H); Mass spectrum MH+ 491.
