Procedure
The title compound was prepared from 1-(5-tert-butylisoxazol-3-yl)-3-(3-mercaptophenyl)urea described in Example 44A (87 mg, 0.3 mmol) and 4-chloro-6,7-difluoroquinazoline (60 mg, 0.3 mmol) from Example 4A Step 2 as described in Example 46 to give 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6,7-difluoro quinazolin-4-ylthio)phenyl)urea (50 mg, 0.11 mmol, 37%). 1H NMR (300 MHz, DMSO-d6) δ 9.61 (s, 1H), 9.05 (s, 1H), 8.88 (s, 1H), 8.34 (dd, 1H), 8.09 (dd, 1H), 7.88 (s, 1H), 7.53 (d, 1H), 7.47 (t, 1H), 7.30 (d, 1H), 6.49 (s, 1H), 1.28 (s, 9H); LC-MS (ESI) m/z 478 (M+Na)+.
