Procedure

A mixture of 111g (1 g, 2.4 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 (1.3 g, 2.68 mmol), PdCl2(dppf) (190 mg, 0.24 mmol), K3PO4 (1 g, 4.8 mmol), and NaOAc (390 mg, 4.8 mmol) in MeCN (15 mL) and H2O (1.5 mL) was heated at 110° C. for 3 h. The solvent was evaporated in vacuo. The residue was purified on silica gel column (DCM:MeOH=50:1) to give 111h (0.8 g, yield 45%).
