Procedure

The title compound was prepared as described in Example 103C, using 1-(5-tert-butylisoxazol-3-yl)-3-{3-[6-methoxy-7-(piperidin-4-yloxy)quinazolin-4-yloxy]phenyl}urea (0.213 g, 0.4 mmol), 2,2,2-trifluoroethyl trifluoromethanesulfonate (0.139 g, 0.6 mmol), and N,N-diisopropylethylamine (0.5 mL) in CH2Cl2 (10 mL) at room temperature for 4 hours, which was purified by silica gel chromatography with EtOAc/hexane as eluants and preparative HPLC (C18 column and 60-90% MeCN/H2O with 0.05% AcOH) to afford 1-(5-tert-butylisoxazol-3-yl)-3-(3-{6-methoxy-7-[1-(2,2,2-trifluoroethyl)piperidin-4-yloxy]quinazolin-4-yloxy}phenyl)urea as a solid (0.027 g, 11%). 1H NMR (300 MHz, CDCl3) δ 9.42 (s, 1H), 8.61 (s, 1H), 7.66 (t, 1H), 7.59 (m, 1H), 7.55 (s, 1H), 7.40 (t, 1H), 7.31 (m, 2H), 7.02 (d, 1H), 5.83 (s, 1H), 4.60 (m, 1H), 4.04 (s, 3H), 3.04 (q, 2H), 3.00 (m, 2H), 2.67 (m, 2H), 2.15 (m, 2H), 2.02 (m, 2H), 1.33 (s, 9H); LC-MS (ESI) m/z 615 (M+H)+.
