Procedure
Using the procedure described in Example 162B, phenyl 5-(1,3-difluoro-2-methylpropan-2-yl)isoxazol-3-ylcarbamate as described in Example 162A (0.089 g, 0.3 mmol) was reacted with 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline from Example 115B (0.094 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-(6,7-dimethoxyquinazolin-4-ylthio)phenyl]urea as solid (0.048 g, 31%). 1H NMR (300 MHz, DMSO-d6) δ 9.71 (s, 1H), 9.02 (s, 1H), 8.70 (s, 1H), 7.85 (d, 1H), 7.52 (d, 1H), 7.46 (t, 1H), 7.35 (d, 2H), 7.29 (d, 1H), 6.78 (s, 1H), 4.72 (s, 2H), 4.56 (s, 2H), 3.99 (s, 6H), 1.29 (s, 3H); LC-MS (ESI) m/z 516 (M+H)+.
