Procedure

In the manner described in Example 159B, ethyl 2-[3-tert-butyl-5-(phenoxycarbonylamino)-1H-pyrazol-1-yl]acetate from the previous step (0.138 g, 0.4 mmol) was reacted with 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline from Example 113A (0.119 g, 0.4 mmol), and N,N-diisopropylethylamine (0.5 mL) in THF (6 mL) at 50° C. for 7 hours, to afford ethyl 2-(3-tert-butyl-5-{3-[3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl]ureido}-1H-pyrazol-1-yl)acetate as solid (0.145 g, 66%). 1H NMR (300 MHz, DMSO-d6) δ 8.97 (s, 1H), 8.59 (s, 1H), 8.56 (s, 1H), 7.59 (m, 1H), 7.56 (s, 1H), 7.39 (m, 2H), 7.22 (d, 1H), 6.94 (d, 1H), 6.11 (s, 1H), 4.85 (s, 2H), 4.16 (q, 2H), 3.99 (s, 6H), 1.19 (t and s, 12H); LC-MS (ESI) m/z 549 (M+H)+.
