3-[(6,7-Dimethoxy-4-quinazolinyl)oxy]aniline → HCID 56954225, compound

Participants

Reaction Steps

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 1-phenyl-3-(1,1,1-trifluoro-2-methylpropan-2-yl)-1H-pyrazol-5-ylcarbamate (104 mg, 0.3 mmol) described in the previous step. The reaction mixture was stirred at rt overnight, then concentrated under reduced pressure. The crude was purified by silica gel chromatography (hexane/ethyl acetate 25-100%) and triturated in diethyl ether to afford 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(1-phenyl-3-(1,1,1-trifluoro-2-methylpropan-2-yl)-1H-pyrazol-5-yl)urea (103 mg, 62%) as a solid. 1H NMR (300 MHz, DMSO-d6) δ 1.56 (s, 6H), 4.02 (s, 6H), 6.55 (s, 1H), 6.94 (d, J=9 Hz, 1H), 7.17 (d, J=9 Hz, 1H), 7.34-7.57 (m, 9H), 8.55-8.59 (m, 2H), 9.28 (s, 1H); LC-MS (ESI) m/z 593 (M+H)+.
