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

Reaction Steps

Using the procedure described in Example 306B, to a solution of 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline (54 mg, 0.18 mmol), prepared as described in Example 113A, in THF (2 ml) was added DMAP (20 mg, 0.16 mmol) and phenyl 3-tert-butyl-1-(6-methylpyridin-3-yl)-1H-pyrazol-5-ylcarbamate (62 mg, 0.18 mmol), described in the previous step, to afford 1-(3-tert-butyl-1-(6-methylpyridin-3-yl)-1H-pyrazol-5-yl)-3-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)urea (59 mg, 60%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.26 (s, 9H), 2.53 (s, 3H), 3.98 (s, 6H), 6.37 (s, 1H), 6.92 (d, J=7.8 Hz, 1H), 7.18 (d, J=8.4 Hz, 1H), 7.36-7.43 (m, 3H), 7.54-7.55 (m, 2H), 7.83 (d, J=8.4 Hz, 1H), 8.51 (s, 1H), 8.55 (s, 1H), 8.61 (d, J=3 Hz, 1H), 9.18 (s, 1H); LC-MS (ESI) m/z 554 (M+H)+.
