Reaction Steps

Using the procedure described in Example 113C, 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline from Example 113A (104 mg, 0.35 mmol) and the carbamate from the previous step (124 mg, 0.45 mmol) were reacted in the presence of N,N-diisopropylethylamine (73 μl, 0.42 mmol) to give 143-cyclopentylisoxazol-5-yl)-3-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)urea (75.22 mg, 45%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 10.18 (s, 1H), 9.05 (s, 1H), 8.56 (s, 1H) 7.57 (s, 2H), 7.56-7.39 (t, 2H) 7.29 (d, 1H), 6.98 (d, 1H), 5.95 (s, 1H), 4.00 (s, 6H), 3.04-3.01 (m, 1H), 1.99-1.93 (m, 2H), 1.69-1.61 (m, 6H)); LC-MS (ESI) m/z 476 (M+H)+.
