Procedure

To a stirred solution of 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline described in Example 115B (144 mg, 0.46 mmol) in anhydrous THF (5.6 mL), was added 4-chlorophenyl 5-(1,1,1-trifluoro-2-methylpropan-2-yl)isoxazol-3-ylcarbamate described in Example 259A (161 mg, 0.46 mmol) and 4-(dimethylamino)pyridine (31 mg, 0.25 mmol). The mixture was stirred at rt for 15 h. To the suspension was added diethyl ether. Sonication and filtration afforded 1-(3-(6,7-dimethoxyquinazolin-4-ylthio)phenyl)-3-(5-(1,1,1-trifluoro-2-methylpropan-2-yl)isoxazol-3-yl)urea (134 mg, 55%) as a colorless solid. 1H NMR (300 MHz, DMSO-d6) δ 9.77 (s, 1H), 9.04 (s, 1H), 8.70 (s, 1H), 7.86 (s, 1H), 7.28-7.54 (m, 5H), 6.89 (s, 1H), 3.99 (s, 6H), 1.54 (s, 6H); LC-MS (ESI) m/z 534 (M+H)+.
