Reaction Steps

The title compound was prepared as described in Example 162B, using phenyl 1-p-tolyl-3-(trifluoromethyl)-1H-pyrazol-5-ylcarbamate described in Example 172B (0.145 g, 0.4 mmol), 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline from Example 115B (0.125 g, 0.4 mmol), and 4-(dimethylamino)pyridine (0.025 g) in THF (6 mL), to afford 1-[3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl]-3-[1-p-tolyl-3-(trifluoromethyl)-1H-pyrazol-5-yl]urea as solid (0.192 g, 83%). 1H NMR (300 MHz, DMSO-d6) δ 9.32 (s, 1H), 8.74 (s, 1H), 8.69 (d, 1H), 7.78 (s, 1H), 7.45 (m, 6H), 7.35 (s, 1H), 7.33 (s, 1H), 7.25 (d, 1H), 6.85 (s, 1H), 3.99 (s, 6H), 2.41 (s, 3H); LC-MS (ESI) m/z 581 (M+H)+.
