Reaction Steps

Using the procedure described in Example 159B, phenyl 1-methyl-5-(trifluoromethyl)-1H-pyrazol-3-ylcarbamate described in Example 165A (0.114 g, 0.4 mmol) was reacted with 3-(6-methoxy-7-(2-methoxyethoxy)quinazolin-4-yloxy)aniline from Example 117B (0.137 g, 0.4 mmol), and N,N-diisopropylethylamine (0.5 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-5-(trifluoromethyl)-1H-pyrazol-3-yl]urea as solid (0.028 g, 13%). 1H NMR (300 MHz, CDCl3) δ 9.53 (br, 1H), 8.63 (s, 1H), 7.61 (s, 1H), 7.55 (s, 1H), 7.41 (t, 1H), 7.32 (m, 2H), 7.12 (s, 1H), 7.01 (d, 1H), 6.28 (s, 1H), 4.36 (t, 2H), 4.04 (s, 3H), 3.92 (s and t, 5H), 3.50 (s, 3H); LC-MS (ESI) m/z 533 (M+H)+.
