실험 절차

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 4-chloro-2-(10-fluoro-1-oxo-3,4,6,7,8,9-hexahydropyrido[3,4-b]indolizin-2(1H)-yl)nicotinaldehyde 134c (97 mg, 0.28 mmol), 3-[(1,5-dimethyl-1H-pyrazol-3-yl)amino]-1-methyl-5-(tetramethyl-1,3,2-dioxaborolan-2-yl)-1,2-dihydropyridin-2-one 218a (192.6 mg, 0.56 mmol), Pd2(dba)3 (54.9 mg, 0.060 mmol), tri(cyclohexyl)phosphine (50.2 mg, 0.18 mmol), Cs2CO3 (182.6 mg, 0.56 mmol), dioxane (8 mL), and water (0.25 mL). After three cycles of vacuum/argon flush, the mixture was stirred at 110° C. for 2 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica-gel column chromatography eluting with 35:1 ethyl acetate/methanol to afford 261a (90 mg, 61%) as a black solid. MS-ESI: [M+H]+ 530.2
