실험 절차

To a 50 mL round bottom flask, 7-bromo-2-chloro-4-morpholin-4-yl-quinazoline (0.65 g, 0.0019 mol), 3-methylsulfonylphenylboronic acid (0.35 g, 0.0018 mol), sodium carbonate (0.314 g, 0.0029 mol), DMF (25 mL) and water (6 mL) were added and degassed the reaction vessel with nitrogen for 5-10 min. To the same reaction mixture, Pd(PPh3)2Cl2 (0.069 g, 0.00099 mol) was added and again degassed with nitrogen for 5-10 min. The reaction mixture was stirred at 95° C. for 2 h. The reaction mixture was cooled and diluted with ethyl acetate. The organic layer was washed with water, brine and dried over sodium sulfate. The solvent was removed under reduced pressure to afford the crude product. The crude product was purified; using column chromatography (60-120 silica gel, 50% ethyl acetate in hexane) to yield the desired product [400 mg, 80%]. LC-MS (ESI): Calculated mass: 403.1; Observed mass: 404.0 [M+H]+ (RT: 1.36 min).
