Versuchsvorschrift

A 25-mL round-bottomed flask equipped with a reflux condenser was charged with 309c (120 mg, 0.30 mmol), {3-[(acetoxy)methyl]-2-{4,4-dimethyl-9-oxo-1,10-diazatricyclo[6.4.0.02,6]dodeca-2(6),7-dien-10-yl}pyridin-4-yl}boronic acid 199e (240 mg, 0.60 mmol), K3PO4 (127 mg, 0.60 mmol), sodium acetate monohydrate (82 mg, 0.60 mmol), Pd(dppf)Cl2 (12 mg, 0.015 mmol), and acetonitrile/water (8/0.5 mL). The system was subjected to three cycles of vacuum/nitrogen flush and heated at 100° C. under N2 protection for 2 h. Analysis of the reaction mixture by LCMS showed complete conversion to the desired product. The reaction mixture was cooled to room temperature and concentrated under reduced pressure. The residue was partitioned between dichloromethane (20 mL) and water (10 mL). The water layer was extracted with dichloromethane (2×10 mL). The combined organic extract was dried over Na2SO4, filtered, and concentrated under reduced pressure. The dark residue was purified by silica-gel column chromatography eluting with dichloromethane/methanol (80:1 to 30:1) to afford 309d (150 mg, 74%) as yellow solid. MS-ESI: [M+H]+ 668.9
