Procedure

To 1-(5-tert-butylisoxazol-3-yl)-3-(3-hydroxyphenyl)urea from Example 1A (137 mg, 0.5 mmol) was added 4-chloro-7-methoxyquinazoline (97 mg, 0.5 mmol) according to the procedure described in Example 1B. The resulting compound was dissolved in EtOAc (5 mL) and 4N HCl in dioxane (0.2 mL, 0.8 mmol) was added. The mixture was sonicated, stirred and concentrated in vacuo to give 1-(5-tert-butylisoxazol-3-yl)-3-(3-(7-methoxyquinazolin-4-yloxy)phenyl)urea as the mono-hydrochloride (103 mg, 0.22 mmol, 44%). 1H NMR (300 MHz, DMSO-d6) δ 9.63 (s, 1H), 9.15 (s, 1H), 8.69 (s, 1H), 8.28 (d, 1H), 7.58 (s, 1H), 7.45-7.35 (m, 3H), 7.27 (d, 1H), 6.98 (d, 1H), 6.48 (s, 1H), 3.98 (s, 3H), 1.28 (s, 9H); LC-MS (ESI) m/z 434 (M+H)+.
