Procedure

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 218a (130 mg, 0.44 mmol), (3-(acetoxymethyl)-2-(7,7-dimethyl-1-oxo-3,4,7,8-tetrahydro-1H-cyclo-penta[4,5]pyrrolo[1,2-a]pyrazin-2(6H)-yl)pyridin-4-yl)boronic acid 199e (175 mg, 0.44 mmol), PdCl2(dppf) (36 mg, 0.044 mmol), K3PO4 (343 mg, 1.32 mmol), sodium acetate (108 mg, 1.32 mmol), acetonitrile (10 mL), and water (0.5 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 3 h. It was then filtered and the filtrate was evaporated in vacuo. The residue was purified by silica-gel column chromatography eluting with 1:20 methanol/dichloromethane to afford 218b as a red solid (103 mg, 42%). MS-ESI: [M+H]+ 570.2
