Participants

Reaction Steps

Using the procedure described in Example 306A, to a solution of 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline (89 mg, 0.3 mmol), prepared as described in Example 113A, in THF (3.3 ml) was added DMAP (20 mg, 0.16 mmol) and phenyl 3-tert-butyl-1-(5-fluoropyridin-3-yl)-1H-pyrazol-5-ylcarbamate (159 mg, 0.45 mmol), described in the previous step, to afford 1-(3-tert-butyl-1-(5-fluoropyridin-3-yl)-1H-pyrazol-5-yl)-3-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)urea (84 mg, 50%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.27 (s, 9H), 3.97-3.99 (m, 6H), 6.42 (s, 1H), 6.93 (d, J=7.8 Hz, 1H), 7.20 (d, J=8.1 Hz, 1H), 7.34-7.40 (m, 2H), 7.54 (d, J=5.1 Hz, 2H), 7.98 (d, J=10 Hz, 1H), 8.55 (s, 1H), 8.61-8.71 (m, 3H), 9.24 (s, 1H); LC-MS (ESI) m/z 558 (M+H)+.
