Procedure
Using the procedure described in Example 92A Step 3, using 1-(5-tert-butylisoxazol-3-yl)-3-(3-hydroxyphenyl)urea (0.193 g, 0.7 mmol) from Example 1A, 4-chloro-7-methoxy-5-(tetrahydro-2H-pyran-4-yloxy)quinazoline from the previous step (0.212 g, 0.72 mmol), and Cs2CO3 (0.326 g, 1 mmol) in isopropanol (10 mL) at 60° C. for 4 hours, to afford 1-(5-tert-butylisoxazol-3-yl)-3-{3-[7-methoxy-5-(tetrahydro-2H-pyran-4-yloxy)quinazolin-4-yloxy]phenyl}urea as solid (0.104 g, 28%). 1H NMR (300 MHz, CDCl3) δ 9.4 (s, 1H), 8.58 (s, 1H), 7.94 (s, 1H), 7.56 (s, 1H), 7.37 (d and s, 2H), 6.95 (d and s, 2H), 6.59 (s, 1H), 5.89 (s, 1H), 4.76 (m 1H), 3.99 (m, 2H), 3.96 (s, 3H), 3.66 (m, 2H), 2.06 (m, 2H), 1.95 (m, 2H), 1.33 (s, 9H); LC-MS (ESI) m/z 534 (M+H)+.
