The title compound was prepared from 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline from Example 113A (89 g, 0.3 mmol) and phenyl 3-(2-methoxyethoxy)-5-(trifluoromethyl)phenylcarbamate from Example 117A (160 mg, 0.45 mmol) in the manner described in Example 115C. The final product was purified by column chromatography (25-100% EtOAc/hexanes then 5-10% MeOH/DCM) to give 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(3-(2-methoxyethoxy)-5-(trifluoromethyl)phenyl)urea (150 mg, 0.27 mmol, 90%). 1H NMR (300 MHz, DMSO-d6) δ 9.09 (s, 1H), 9.03 (s, 1H), 8.57 (s, 1H), 7.61-7.57 (m, 2H), 7.49 (s, 1H), 7.43-7.38 (m, 2H), 7.31-7.24 (m, 2H), 6.95 (d, 1H), 6.86 (s, 1H), 4.19-4.11 (m, 2H), 4.00 (s, 3H), 3.99 (s, 3H), 3.70-3.63 (m, 2H), 3.31 (s, 3H); LC-MS (ESI) m/z 559 (M+H)+.
