Reaction Steps

The title compound was prepared from phenyl 1-phenyl-3-(1-(trifluoromethyl) cyclopropyl)-1H-pyrazol-5-ylcarbamate described in Example 137A (129 mg, 0.33 mmol) and 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline described in Example 113A (100 mg, 0.33 mmol) using the procedure described in Example 115C. The crude product was purified by column chromatography (25-100% EtOAc/hexanes) to give 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(1-phenyl-3-(1-(trifluoromethyl)cyclopropyl)-1H-pyrazol-5-yl)urea (139 mg, 0.24 mmol, 71%). 1H NMR (300 MHz, DMSO-d6) δ 9.28 (s, 1H), 8.61 (s, 1H), 8.55 (s, 1H), 7.63-7.51 (m, 6H), 7.48 (d, 1H), 7.39 (s, 1H), 7.37 (t, 1H), 7.17 (d, 1H), 6.93 (d, 1H), 6.55 (s, 1H), 4.00 (s, 3H), 3.98 (s, 3H), 1.31 (d, 4H); LC-MS (ESI) m/z 591 (M+H)+.
