Versuchsvorschrift

A 100-mL round-bottomed flask equipped with a reflux condenser was charged with 229b (277 mg, 0.90 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 (358 mg, 0.90 mmol), Pd(dppf)Cl2 (74 mg, 0.090 mmol), K3PO4 (381 mg, 1.80 mmol), water (2 mL), and tetrahydrofuran (20 mL). After three cycles of vacuum/argon flush, the mixture was heated at reflux for 3 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 60:1 dichloromethane/methanol to afford 229c as white solid (291 mg, 50%). MS-ESI: [M+H]+ 582.4
