Procedure
The title compound was prepared from 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline from Example 113A (90 mg, 0.3 mmol) and phenyl 3-tert-butylphenylcarbamate from the previous step (114 mg, 0.42 mmol) using Example 115C. The final product was purified by silica gel column chromatography (25-100% EtOAc/hexanes) to give 1-(3-tert-butylphenyl)-3-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)urea (83 mg, 0.18 mmol, 58%). 1H NMR (300 MHz, DMSO-d6) δ 8.83 (s, 1H), 8.70 (s, 1H), 8.57 (s, 1H), 7.61 (s, 1H), 7.57 (s, 1H), 7.50-7.36 (m, 3H), 7.31-7.14 (m, 3H), 7.05-6.86 (m, 2H), 4.00 (s, 6H), 1.28 (s, 9H); LC-MS (ESI) m/z 473 (M+H)+.
