実験手順

A stirred mixture of phenyl 3-(perfluoroethyl)-1-phenyl-1H-pyrazol-5-ylcarbamate (199 mg, 0.50 mmol), 3-(6,7-dimethoxyquinazolin-4-yloxy)aniline (prepared as described in Example 113A) (100 mg, 0.34 mmol), N,N-diethylisopropylamine (88 mg, 0.68 mmol) in THF (1 mL) was heated at 60° C. for 15 h. After cooling to rt, the reaction mixture was partitioned between saturated aqueous sodium hydrogen carbonate solution and dichloromethane. The organic layer was separated, dried over magnesium sulfate and concentrated under reduced pressure to afford the crude product. Purification via preparative HPLC afforded 1-(3-(6,7-dimethoxyquinazolin-4-yloxy)phenyl)-3-(3-(perfluoroethyl)-1-phenyl-1H-pyrazol-5-yl)urea (80 mg, 39%) as a colorless solid. 1H NMR (400 MHz, DMSO-d6) δ 9.35 (s, 1H), 8.82 (s, 1H), 8.54 (s, 1H), 7.55-7.61 (m, 7H), 7.36-7.40 (m, 2H), 7.18 (m, 1H), 6.95 (m, 1H), 6.88 (s, 1H), 3.99 (s, 3H), 3.98 (s, 3H); LC-MS (ESI) m/z 601 (M+H)+.
