Participants

Reaction Steps

Using the procedure described in Example 159B, using phenyl 1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-ylcarbamate described in Example 164B (0.114 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 3 hours, to afford 1-{3-[6-methoxy-7-(2-methoxyethoxy)quinazolin-4-yloxy]phenyl}-3-[1-methyl-3-(trifluoromethyl)-1H-pyrazol-5-yl]urea as solid (0.033 g, 15%). 1H NMR (300 MHz, CDCl3) δ 9.5 (br, 1H), 8.63 (s, 1H), 7.60 (m, 1H), 7.55 (s, 1H), 7.32-7.43 (m, 4H), 7.00 (dd, 1H), 6.31 (s, 1H), 4.36 (t, 2H), 4.04 (s, 3H), 3.91 (s and t, 5H), 3.50 (s, 3H); LC-MS (ESI) m/z 533 (M+H)+.
