Reaction Steps

The title compound was prepared as described in Example 162B, using phenyl 5-(1,3-difluoro-2-methylpropan-2-yl)isoxazol-3-ylcarbamate as described in Example 162A (0.089 g, 0.3 mmol), 3-(6-methoxy-7-(2-methoxyethoxy)quinazolin-4-ylthio)aniline from the previous step (0.107 g, 0.3 mmol), and 4-(dimethylamino)pyridine (0.03 g) in THF (6 mL), to afford 1-[5-(1,3-difluoro-2-methylpropan-2-yl)isoxazol-3-yl]-3-{3-[6-methoxy-7-(2-methoxyethoxy)quinazolin-4-ylthio]phenyl}urea as solid (0.038 g, 23%). 1H NMR (300 MHz, DMSO-d6) δ 9.71 (s, 1H), 9.02 (s, 1H), 8.69 (s, 1H), 7.84 (m, 1H), 7.28-7.54 (m, 5H), 6.78 (s, 1H), 4.72 (s, 2H), 4.56 (s, 2H), 4.33 (m, 2H), 3.99 (s, 3H), 3.77 (m, 2H), 3.34 (s 3H), 1.29 (s, 3H); LC-MS (ESI) m/z 560 (M+H)+.
