Procedure

A 25-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 253d (172 mg, 0.46 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 (0.91 g, 2.29 mmol), Pd(dppf)Cl2 (36 mg, 0.050 mmol), K3PO4 (195 mg, 0.92 mmol), sodium acetate (75 mg, 0.050 mmol), water (0.5 mL), and acetonitrile (10 mL). After three cycles of vacuum/argon flush, the mixture was heated at 90° C. for 2 h. It was then cooled to room temperature and filtered. The filtrate was evaporated under reduced pressure and the resulting residue was purified by silica-gel column chromatography eluting with 20:1 ethyl acetate/methanol to afford the 253e (100 mg, 31%) as brown solid. MS-ESI: [M+H]+ 694.3.
