Product 1

HCID 582678351-(5-Tert-butyl isoxazol-3-yl)-3-(3-(6-methoxyquinazolin-4-ylthio)phenyl)urea

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-methoxyquinazoline (59 mg, 0.3 mmol) as described in Example 46 and its corresponding hydrochloride salt was prepared as described in Example 4B Step 2 to give 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-methoxyquinazolin-4-ylthio)phenyl)urea as the mono-hydrochloride (76 mg, 0.15 mmol, 50%). 1H NMR (300 MHz, DMSO-d6) δ 9.75 (s, 1H), 9.49 (s, 1H), 8.80 (s, 1H), 7.95 (d, 1H), 7.87 (s, 1H), 7.71 (dd, 1H), 7.55 (d, 1H), 7.49-7.42 (m, 2H), 7.29 (d, 1H), 6.50 (s, 1H), 4.00 (s, 3H), 1.28 (s, 9H); LC-MS (ESI) m/z 450 (M+H)+.
