Following Example 121b, 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 (338 mg, 0.7 mmol), 202a (181 mg, 0.5 mmol), 1M sodium carbonate solution (2 mL, 2 mmol), tetrakis(triphenylphosphine)palladium(0) (29 mg, 0.025 mmol) and 1,2-dimethoxyethane (5 mL) were reacted. Work-up and flash column chromatography (silica, 3:1 methylene chloride/methanol) give a mixture (200 mg) of 4-fluoro-2-(1-methyl-5-(5-(1-methylpyrrolidin-2-yl)pyridin-2-ylamino)-6-oxo-1,6-dihydropyridin-3-yl)-6-(1-oxo-3,4,6,7,8,9-hexahydropyrazino[1,2-a]indol-2(1H)-yl)benzyl acetate and 202 as a yellow residue.
