Using the procedure described in Example 306A, to a solution of 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline (125 mg, 0.4 mmol), prepared as described in Example 115B, in THF (2 ml) was added DMAP (20 mg, 0.16 mmol) and phenyl 3-isopropyl-1-phenyl-1H-pyrazol-5-ylcarbamate (129 mg, 0.4 mmol) described in Example 324A. The suspension was filtered and triturated with anhydrous diethyl ether to afford 1-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)-3-(3-isopropyl-1-phenyl-1H-pyrazol-5-yl)urea (154 mg, 71%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.22 (d, J=7.2 Hz, 6H), 2.88 (m, 1H), 3.99 (s, 6H), 6.32 (s, 1H), 7.24 (d, J=7.5 Hz, 1H), 7.25-7.53 (m, 10H), 7.79 (m, 1H), 8.47 (s, 1H), 8.69 (s, 1H), 9.21 (s, 1H); LC-MS (ESI) m/z 541 (M+H)+.
