Reaction Steps

The title compound was prepared from 1-(3-(2-fluoropropan-2-yl)isoxazol-5-yl)-3-(3-hydroxyphenyl)urea (84 mg, 0.3 mmol) and 4-chloro-7-methoxy-6-(3-(methylsulfonyl)propoxy)quinazoline from Example 41B Step 1 (76 mg, 0.23 mmol) using the procedure described in Example 16C. The crude product was purified by chromatography on silica gel (25-100% EtOAc/hexanes) to afford 1-(3-(2-fluoropropan-2-yl)isoxazol-5-yl)-3-(3-(7-methoxy-6-(3-(methylsulfonyl)propoxy)quinazolin-4-yloxy)phenyl)urea (81 mg, 0.14 mmol, 61%). 1H NMR (300 MHz, DMSO-d6) δ 10.42 (br s, 1H), 9.11 (s, 1H), 8.57 (s, 1H), 7.63-7.58 (m, 2H), 7.47-7.40 (m, 2H), 7.32 (d, 1H), 7.00 (d, 1H), 6.15 (s, 1H), 4.32 (t, 2H), 4.02 (s, 3H), 3.41-3.29 (m, 2H), 3.06 (s, 3H), 2.31-2.22 (m, 2H), 1.66 (d, 6H); LC-MS (ESI) m/z 574 (M+H)+.
