실험 절차

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 295a (24.8 mg, 0.222 mmol), [4-(5-bromo-1-methyl-6-oxo-1,6-dihydropyridin-3-yl)-2-{4,4-dimethyl-9-oxo-1,10-diazatri-cyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-3-yl]methyl acetate 273a (100 mg, 0.185 mmol), Pd2(dba)3 (8.5 mg, 0.0093 mmol), Xantphos (10.7 mg, 0.019 mmol), Cs2CO3 (120.6 mg, 0.37 mmol), and dioxane (10 mL). The system was subjected to three cycles of vacuum/nitrogen flush and heated at 100° C. under N2 protection for 3 h. Analysis of the reaction mixture by LCMS showed complete conversion to the desired product. It was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was washed with acetonitrile (0.5 mL) to afford 295b as white solid (52 mg, 49.5%), which was used in the next step without further purification. MS-ESI: [M+H]+ 570.8
