Procedure

A sealed tube was charged with the mixture of 2-(1-oxo-3,4,6,7,8,9-hexa-hydropyrazino[1,2-a]indol-2(1H)-yl)-6-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzyl acetate 114a (232 mg, 0.5 mmol), 148a (148 mg, 0.50 mmol), Pd(dppf)Cl2 (25 mg, 0.03 mmol), K3PO4.3H2O(266 mg, 1.0 mmol), and NaOAc (82 mg, 1.0 mmol) in CH3CN (18 mL). The system was evacuated and refilled with N2. The reaction mixture was heated at 110° C. for 2 h. It 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 30:1 DCM/MeOH to afford 148b as a yellow solid (200 mg, 72%). MS: [M+H]+ 556.
