실험 절차

Suspended 5-chloro-3-(4-methoxy-benzyl)-3,4-dihydro-1h-pyrido[2,3-d]pyrimidin-2-one (400.00 mg; 1.32 mmol; 1.00 eq.), 3-amino-1-methyl-1h-indazol-6-ol (268.61 mg; 1.65 mmol; 1.25 eq.) and cesium carbonate (858.15 mg; 2.63 mmol; 2.00 eq.) in DMF (4.00 ml). Heated in a microwave at 130° C. for 90 min. The reaction was concentrated, redissolved in DMSO (20 mL) and filtered through celite. Purified filtrate via prep HPLC to afford 400 mg (56%) of compound 276 as a tan solid. LC-MS (M+H=431, obsd.=431)
