実験手順

To a solution of 1-(5-tert-butylisoxazol-3-yl)-3-(3-(6-hydroxy-7-methoxyquinazolin-4-yloxy)phenyl)urea (120 mg, 0.267 mmol) in DMF (4 mL), Cs2CO3 (0.32 mmol) and (S) (+) epichlorohydrin (104 μL, 1.33 mmol) was added. The reaction mixture was reacted at 80 C under microwave condition for 2 h. The mixture was diluted with a ethyl acetate/THF (15/5) mixture and washed with water, brine and dried over MgSO4. After removal of the solvent, the titled compound was obtained as an off-white solid. Yield: 135 mg (100%). LC-MS (ESI) m/z 506 (M+H)+.
