Procedure

To 1-(5-tert-butylisoxazol-3-yl)-3-(3-hydroxyphenyl)urea from Example 1A (275 mg, 1 mmol) was added 4-chloro-6-methoxyquinazoline (194 mg, 1 mmol) according to the procedure described in Example 1B Step 1. The resulting compound was dissolved in EtOAc and 4N HCl in dioxane was added. The mixture was sonicated, stirred and concentrated in vacuo to give 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-methoxyquinazolin-4-yloxy)phenyl)urea as the mono-hydrochloride (299 mg, 0.64 mmol, 64%). 1H NMR (300 MHz, DMSO-d6) δ 9.65 (s, 1H), 9.20 (s, 1H), 8.65 (s, 1H), 7.95 (d, 1H), 7.75-7.60 (m, 3H), 7.42 (t, 1H), 7.29 (d, 1H), 6.98 (d, 1H), 6.48 (s, 1H), 3.98 (s, 3H), 1.29 (s, 9H); LC-MS (ESI) m/z 434 (M+H)+.
