Procedure
To a solution of 1-(5-tert-butyl-isoxazol-3-yl)-3-{3-[7-(2-chloro-ethoxy)-6-methoxy-quinazolin-4-yloxy]-phenyl}-urea from Example 35B (225 mg, 0.439 mmol) in DMF (3 mL) was added morpholine (114.86 mg, 1.318 mmol) followed by diisopropylethylamine (0.229 mL, 1.318 mmol) and tetrabutylammonium iodide (162.3 mg, 0.439 mmol). The reaction mixture was heated at 60° C. for 3 days. Formation of product was determined by LCMS. The crude reaction mixture was purified by preparative HPLC (phenomenex phenylhexyl reverse phase column eluted with gradient of solvent A=0.05% HOAc/H2O and solvent B=0.05% HOAc/CH3CN) to afford 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-methoxy-7-(2-morpholinoethoxy)quinazolin-4-yloxy)phenyl)urea (51 mg, 21%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 9.58 (s, 1H), 9.00 (s, 1H), 8.55 (s, 1H), 7.60-7.35 (m, 4H), 7.25 (m, 1H), 6.95 (m, 1H), 6.45 (s, 1H), 4.32 (m, 2H), 3.95 (s, 3H), 3.62 (m, 4H), 2.85 (m, 2H), 2.65-2.45 (m, 4H), 1.28 (s, 9H); LC-MS (ESI) m/z 563 (M+H)+.
