Reaction Steps

To 3-(6,7-dimethoxyquinazolin-4-ylthio)aniline from the previous step (94 mg, 0.3 mmol) in THF (3 mL) was added phenyl 3-methoxy-5-(trifluoromethyl)phenylcarbamate from Example 115A (140 mg, 0.45 mmol), diisopropylethylamine (80 uL, 0.45 mmol), and 4-dimethylaminopyridine (4 mg, 0.03 mmol). The solution was stirred at 50° C. overnight, allowed to cool to room temperature, and diluted with EtOAc. The solid was then filtered to give 14346,7-dimethoxyquinazolin-4-ylthio)phenyl)-3-(3-methoxy-5-(trifluoromethyl)phenyl)urea (89 mg, 0.17 mmol, 56%). 1H NMR (300 MHz, DMSO-d6) δ 9.12 (s, 1H), 9.02 (s, 1H), 8.70 (s, 1H), 7.84 (s, 1H), 7.55 (d, 1H), 7.48 (s, 1H), 7.44 (t, 1H), 7.35 (s, 1H), 7.34 (s, 1H), 7.29-7.24 (m, 2H), 6.85 (s, 1H), 3.99 (s, 6H), 3.81 (s, 3H); LC-MS (ESI) m/z 531 (M+H)+.
