実験手順

A sealed tube equipped with a magnetic stirrer was charged with (S)-5-bromo-3-(5-(2-ethyl-4-(oxetan-3-yl)piperazin-1-yl)pyridin-2-ylamino)-1-methylpyridin-2(1H)-one (203 mg, 0.45 mmol), 4-fluoro-2-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl acetate (216 mg, 0.45 mmol), Pd(dppf)Cl2 (18 mg, 0.0225 mmol), NaOAc (74 mg, 0.90 mmol), K3PO4 (191 mg, 0.90 mmol), and acetonitrile (3 mL). See FIG. 5. After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 1 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica gel column chromatography eluting with dichloromethane/methanol (25:1, V/V) to afford 105a (220 mg, 87%) as a brown solid. LCMS: [M+H]+ 724
