Procedure

A 50-mL round-bottomed flask equipped with a reflux condenser was charged with 264b (170 mg, 0.50 mmol), (3-(acetoxymethyl)-2-(7,7-dimethyl-1-oxo-3,4,7,8-tetrahydro-1H-cyclopenta[4,5]pyrrolo[1,2-a]pyrazin-2(6H)-yl)pyridin-4-yl)boronic acid 199e (200 mg, 0.50 mmol), Pd(dppf)Cl2 (40 mg, 0.050 mmol), K3PO4 (212 mg, 1.0 mmol), water (0.5 mL), and tetrahydrofuran (10 mL). After three cycles of vacuum/argon flush, the mixture was heated at reflux for 6 h. It was then cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 40:1 dichloromethane/methanol to afford 264c as brown solid (200 mg, 54%). MS-ESI: [M+H]+ 612.3
