Procedure

A sealed tube was charged with the mixture of 331a (400 mg, 1 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 210d (578 mg, 1.2 mmol), Pd(dppf)Cl2 (82 mg, 0.1 mmol), K3PO4.3H2O(760 mg, 2 mmol), and NaOAc (164 mg, 2 mmol) in CH3CN (10 mL). The system was evacuated and then refilled with N2 and the reaction mixture was heated at 110° C. for 2 h. The mixture was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by flash column chromatography eluting with 50:1 methylene chloride/methanol to afford 331b as a yellow solid (100 mg, 14%). MS: [M+H]+ 655.
