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 (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 Example 326A to afford 1-(3-tert-butyl-1-(5-fluoropyridin-3-yl)-1H-pyrazol-5-yl)-3-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)urea (107 mg, 62%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.28 (s, 9H), 3.99 (m, 6H), 6.43 (s, 1H), 7.25 (d, J=7.5 Hz, 1H), 7.34 (d, J=4.5 Hz, 2H), 7.38-7.47 (m, 2H), 7.54 (s, 1H), 7.98 (d, J=9.9 Hz, 1H), 8.61-8.72 (m, 4H), 9.25 (s, 1H); LC-MS (ESI) m/z 574 (M+H)+.
