Participants

Reaction Steps

Using the procedure described in Example 159B, using phenyl 1-phenyl-3-(trifluoromethyl)-1H-pyrazol-5-ylcarbamate from Example 161C (0.139 g, 0.4 mmol), 3-(6-methoxy-7-(2-methoxyethoxy)quinazolin-4-yloxy)aniline from Example 117B (0.137 g, 0.4 mmol), and N,N-diisopropylethylamine (0.3 mL) in THF (6 mL) at 50° C. for 6 hours, to afford 1-{3-[6-methoxy-7-(2-methoxyethoxy)quinazolin-4-yloxy]phenyl}-3-[1-phenyl-3-(trifluoromethyl)-1H-pyrazol-5-yl]urea as solid (0.115 g, 48%). 1H NMR (300 MHz, DMSO-d6) δ 9.32 (s, 1H), 8.81 (s, 1H), 8.54 (s, 1H), 7.49-7.62 (m, 7H), 7.38 (m, 2H), 7.20 (d, 1H), 6.95 (d, 1H), 6.87 (s, 1H), 4.38 (m, 2H), 3.98 (s, 3H), 3.78 (m, 2H), 3.35 (s, 3H); LC-MS (ESI) m/z 595 (M+H)+.
