실험 절차

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with (S)-5-bromo-1-methyl-3-(5-(2-methyl-4-(oxetan-3-yl)piperazin-1-yl)pyrazin-2-ylamino)pyridin-2(1H)-one 230f (200 mg, 0.46 mmol), {3-[(acetoxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]-dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (366 mg, 0.92 mmol), Pd(dppf)Cl2 (38 mg, 0.046 mmol), sodium acetate (126 mg, 0.92 mmol), K3PO4 (196 mg, 0.92 mmol), water (0.5 mL), and acetonitrile (10 mL). After three cycles of vacuum/argon flush, the mixture was heated at 65° C. for 3 hrs. After cooling to room temperature the reaction was filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with dichloromethane/methanol (50:1 to 30:1) to afford 235a as brown solid (100 mg, 31%). MS-ESI: [M+H]+ 708.5.
