Procedure
3-(6,7-Dimethoxyquinazolin-4-yloxy)aniline from Example 113A (90 mg, 0.302 mmol) and 4-chlorophenyl 5-(2-fluoropropan-2-yl)isoxazol-3-ylcarbamate from the previous step (90 mg, 0.302 mmol) were reacted according to the procedure described in Example 122B, except the reaction mixture was stirred at room temperature for 3 h. The crude material was purified via silica gel chromatography (0%-10% methanol in dichloromethane) to afford 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(5-(2-fluoropropan-2-yl)isoxazol-3-yl)urea as a colorless solid (37 mg, 26%). 1H NMR (300 MHz, DMSO-d6) δ 9.75 (brs, 1H), 9.04 (brs, 1H), 8.56 (s, 1H), 7.56-7.58 (m, 2H), 7.40-7.41 (m, 2H), 7.29 (m, 1H), 7.00 (m, 1H), 6.86 (s, 1H), 4.00 (s, 6H), 1.72 (d, J=21 Hz, 6H); LC-MS (ESI) m/z 468 (M+H)+.
