Reaction Steps

To 1-(5-tert-butylisoxazol-3-yl)-3-(3-mercaptophenyl)urea described in Example 44A (1.07 g, 3.70 mmol) was added 4-chloro-6-(2-chloroethoxy)-7-methoxyquinazoline (1.0 g, 3.70 mmol) from Example 16B according to the procedure described in Example 46 to give 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-(2-chloroethoxy)-7-methoxyquinazolin-4-ylthio)phenyl)urea (1.54 g, 2.92 mmol, 79%). 1H NMR (300 MHz, DMSO-d6) δ 9.59 (s, 1H), 9.02 (s, 1H), 8.71 (s, 1H), 7.85 (s, 1H), 7.51 (d, 1H), 7.44 (t, 1H), 7.38 (s, 2H), 7.28 (d, 1H), 6.49 (s, 1H), 4.50 (t, 2H), 4.07 (t, 2H), 4.01 (s, 3H), 1.29 (s, 9H); LC-MS (ESI) m/z 528 (M+H)+.
