Procedure
As described in Example 50, a mixture of the intermediate 1-(5-tert-butylisoxazol-3-yl)-3-(3-mercaptophenyl)urea described in Example 44A (0.117 g, 0.4 mmol), 4-chloro-6,7-bis(2-methoxyethoxy)quinazoline (0.125 g, 0.4 mmol) from Example 12A, and Cs2CO3 (0.20 g, 0.6 mmol) in isopropanol (5 mL) was heated at 90° C. overnight, to afford 1-{3-[6,7-bis(2-methoxyethoxy)quinazolin-4-ylthio]phenyl}-3-(5-tert-butylisoxazol-3-yl)urea. as solid. 1H NMR (300 MHz, DMSO-d6) δ 9.58 (s, 1H), 8.99 (s, 1H), 8.68 (s, 1H), 7.84 (m, 1H), 7.51 (m, 1H), 7.46 (t, 1H), 7.39 (s, 1H), 7.38 (s, 1H), 7.28 (dd 1H), 6.49 (s, 1H), 4.34 (m 4H), 3.78 (m, 4H), 3.37 (s, 3H), 3.35 (s, 3H), 1.28 (s, 9H).
