3-(6,7-Dimethoxyquinazolin-4-ylthio)aniline → 1-(3-(6,7-dimethoxyquinazolin-4-ylthio)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-ylthio)aniline (94 mg, 0.3 mmol), prepared as described in Example 115B, in THF (3.3 ml) was added DMAP (23 mg, 0.18 mmol) and phenyl 3-isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5-ylcarbamate (105 mg, 0.3 mmol), described in Example 348A, to afford 1-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)-3-(3-isopropyl-1-(4-methoxyphenyl)-1H-pyrazol-5-yl)urea (101 mg, 59%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.21 (d, J=7 Hz, 6H), 2.86 (s, 1H), 3.81 (s, 3H), 3.99 (s, 6H), 6.28 (s, 1H), 7.07 (d, J=8.7 Hz, 2H), 7.23 (d, J=7.5 Hz, 1H), 7.34 (d, J=5 Hz, 2H), 7.39-7.44 (m, 4H), 7.79 (s, 1H), 8.35 (s, 1H), 8.68 (s, 1H), 9.18 (s, 1H); LC-MS (ESI) m/z 571 (M+H)+.
