Procedure

To a slurry of sodium hydride (7.5 mg, 0.3 mmol) in DMF (3 mL) was added 1-(5-tert-butylisoxazol-3-yl)-3-(3-mercaptophenyl)urea described in Example 44A (90 mg, 0.3 mmol), and the solution stirred at room temperature When gas evolution ceased, 2,4-dichloro-6,7-dimethoxyquinazoline (78 mg, 0.3 mmol) was added and the solution heated at 50° C. overnight, cooled to room temperature, and diluted with H2O. The mixture was extracted with EtOAc, the organic layer washed with aqueous sat. NaHCO3 and brine, dried over MgSO4, filtered and concentrated in vacuo. The crude solid was purified by HPLC to give 1-(5-tert-butylisoxazol-3-yl)-3-(3-(2-chloro-6,7-dimethoxyquinazolin-4-ylthio)phenyl)urea (20 mg, 0.04 mmol, 13%). 1H NMR (300 MHz, DMSO-d6) δ 9.79 (s, 1H), 9.53 (s, 1H), 7.90 (s, 1H), 7.62 (d, 1H), 7.44 (t, 1H), 7.36 (s, 2H), 7.27 (d, 1H), 6.49 (s, 1H), 4.00 (s, 6H), 1.28 (s, 9H); LC-MS (ESI) m/z 514 (M+H)+.
