Procedure

According to the procedure described in Example 50, a mixture of 1-(5-tert-butylisoxazol-3-yl)-3-(3-hydroxyphenyl)urea (4.405 g, 16 mmol) from Example 1A, 4-chloro-6-methoxy-7-(2-methoxyethoxy)quinazoline from Example 7A (4.837 g, 18 mmol), and Cs2CO3 (8.145 g, 16 mmol) in isopropanol (80 mL) was heated at 70° C. for 4 hours, to afford 1-(5-tert-butylisoxazol-3-yl)-3-{3-[6-methoxy-7-(2-methoxyethoxy)quinazolin-4-yloxy]phenyl}urea as a solid (5.548 g, 68.3%). 1H NMR (300 MHz, DMSO-d6) δ 9.58 (s, 1H), 9.00 (s, 1H), 8.57 (s, 1H), 7.58 (m, 2H), 7.41 (m, 2H), 7.25 (d, 1H), 6.98 (d, 1H), 6.48 (s, 1H), 4.34 (t, 2H), 3.99 (s, 3H), 3.78 (t, 2H), 3.35 (s, 3H), 1.28 (s, 9H); LC-MS (ESI) m/z 508 (M+H)+.
