Reaktionsschritte

A suspension of 5-chloro-3-(4-methoxy-benzyl)-3,4-dihydro-1h-pyrido[2,3-d]pyrimidin-2-one (100.00 mg; 0.33 mmol; 1.00 eq.), 4-quinoxalin-2-ylphenol (91.46 mg; 0.41 mmol; 1.25 eq.), and cesium carbonate (214.54 mg; 0.66 mmol; 2.00 eq.) in DMF (2.00 ml) was heated in a microwave at 130° C. for 4 hours. The reaction was concentrated, redissolved in DMSO, syringe filtered, and purified via prep HPLC to afford 69 mg of 280 as an off-white solid. LC-MS (M+H=490, obsd.=490).
