Procedure

To 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline from Example 113A (89 mg, 0.3 mmol) in THF (3 mL) was added phenyl isocyanate (33 uL, 0.3 mmol) and the solution stirred at room temperature overnight. The reaction was concentrated in vacuo, diluted with EtOAc, and filtered to give 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-phenylurea (63 mg, 0.15 mmol, 50%). 1H NMR (300 MHz, DMSO-d6) δ 8.88 (s, 1H), 8.74 (s, 1H), 8.57 (s, 1H), 7.61-7.56 (m, 2H), 7.48-7.35 (m, 4H), 7.32-7.21 (m, 3H), 7.02-7.89 (m, 2H), 3.99 (s, 6H); LC-MS (ESI) m/z 417 (M+H)+.
