実験手順

To a solution of 1-(5-tert-butyl-isoxazol-3-yl)-3-{3-[7-(2-chloro-ethoxy)-6-methoxy-quinazolin-4-ylsulfanyl]-phenyl}-urea from Example 79A (225 mg, 0.426 mmol) in DMF (3 mL) was added piperidine (0.126 mL, 1.278 mmol) followed by diisopropyl ethylamine (0.222 mL, 1.278 mmol) and tetrabutyl ammonium iodide (157.35 mg, 0.426 mmol). The reaction mixture was heated at 60° C. for 2 days. Formation of product was determined by LCMS. The crude reaction mixture was purified by preparative HPLC (using 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-(piperidin-1-yl)ethoxy)quinazolin-4-ylthio)phenyl)urea (42 mg, 17%) as a white solid. 1H NMR (300 MHz, DMSO-d6) δ 9.60 (s, 1H), 9.20 (s, 1H), 8.65 (s, 1H), 7.85 (s, 1H), 7.60-7.22 (m, 5H), 6.45 (s, 1H), 4.30 (m, 2H), 3.95 (s, 3H), 2.85-2.30 (m, 6H), 1.70-1.30 (m, 6H), 1.25 (s, 9H); LC-MS (ESI) m/z 577 (M+H)+.
