Using the procedure described in Example 306B, to a solution of 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline (92 mg, 0.31 mmol), prepared as described in Example 113A, in THF (2 ml) was added DMAP (20 mg, 0.16 mmol) and phenyl 3-isopropyl-1-phenyl-1H-pyrazol-5-ylcarbamate (100 mg, 0.31 mmol) described in the previous step. The suspension was triturated with anhydrous diethyl ether to afford 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(3-isopropyl-1-phenyl-1H-pyrazol-5-yl)urea (98 mg, 60%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.21 (d, J=6.9 Hz, 6H), 2.87 (m, 1H), 3.99 (s, 6H), 6.31 (s, 1H), 6.92 (d, J=7.8 Hz, 1H), 7.18 (d, J=7.8 Hz, 1H), 7.34-7.40 (m, 3H), 7.52-7.55 (m, 6H), 8.47 (s, 1H), 8.55 (s, 1H), 9.21 (s, 1H); LC-MS (ESI) m/z 525 (M+H)+.
