The procedure described in Example 20 was repeated using (3R,5S)-5-[({4-[3-chloro-4-fluoroanilino]-7-methoxyquinazolin-5-yl}oxy)methyl]pyrrolidin-3-ol (209 mg) with glycolic acid (42 mg) to give the title compound as a white solid in 53% yield; NMR spectrum (DMSO-d6) 10.17 (s, 1H), 8.53 (s, 1H), 8.14 (dd, 1H), 7.74-7.69 (m, 1H), 7.47 (t, 1H), 6.92 (d, 1H), 6.83 (d, 1H), 5.14-5.10 (m, 1H), 4.71-4.67 (m, 1H), 4.50-4.44 (m, 1H), 4.40-4.38 (m, 1H), 4.28-4.23 (m, 1H), 4.06-4.03 (m, 2H), 3.95 (s, 3H), 3.53-3.48 (m, 3H), 2.05-2.02 (m, 2H); Mass spectrum MH+ 477.
