Versuchsvorschrift

A round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 4-chloro-2-{6-oxo-8-thia-4,5-diazatricyclo[7.4.0.02,6]trideca-1(9),2(7),3-trien-5-yl}pyridine-3-carbaldehyde 124a (138 mg, 0.40 mmol), 216a (240 mg, 0.60 mmol), PdCl2(dppf) (20 mg, 0.020 mmol), K3PO4 (180 mg, 0.80 mmol), sodium acetate trihydrate (120 mg, 0.80 mmol), water (6 drops), and acetonitrile (15 mL). After three cycles of vacuum/argon flush, the mixture was heated at 100° C. for 2 h. Then, it was cooled to room temperature and filtered. The filtrate was evaporated under reduced pressure and the residue was purified by silica-gel column chromatography eluting with 25:1 dichloromethane/methanol to afford 216b as a yellow solid (100 mg, 45%). MS-ESI: [M+H]+ 586.2.
