Reaction Steps
A sealed tube was charged with the mixture of 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 210d (230 mg, 0.48 mmol), 5-bromo-3-(5-(methoxymethyl)-1-methyl-1H-pyrazol-3-ylamino)-1-methylpyridin-2(1H)-one 176c (156 mg, 0.48 mmol), Pd(dppf)Cl2 (39 mg, 0.048 mmol), Na2CO3 (101 mg, 0.96 mmol) in DMF (18 mL). The system was evacuated and then refilled with N2. And the reaction mixture was heated at 110° C. for 2 h. Then, the mixture was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by column chromatography eluting with 15:1 methylene chloride/methanol to give 178a as a brown solid (160 mg, 53%). MS: [M+H]+ 603.
