3-[(6,7-Dimethoxy-4-quinazolinyl)oxy]aniline → 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(3-isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5-yl)urea

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-isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5-ylcarbamate (105 mg, 0.3 mmol), described in the previous step, to afford 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(3-isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5-yl)urea (65 mg, 39%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.20 (d, J=7 Hz, 6H), 2.85 (m, 1H), 3.81 (s, 3H), 3.97 (s, 6H), 6.27 (s, 1H), 6.91 (d, J=7.5 Hz, 1H), 7.07 (d, J=9 Hz, 2H), 7.16 (d, J=9 Hz, 1H), 7.33-7.41 (m, 4H), 7.55 (s, 2H), 8.35 (s, 1H), 8.55 (s, 1H), 9.18 (s, 1H); LC-MS (ESI) m/z 555 (M+H)+.
