Versuchsvorschrift

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 335b (240 mg, 0.60 mmol), 4-chloro-2-{4,4-dimethyl-9-oxo-7-thia-10,11-diazatricyclo[6.4.0.02,6]dodeca-1(8),2(6),11-trien-10-yl}pyridine-3-carbaldehyde 282i (107.7 mg, 0.30 mmol), Pd(dppf)Cl2 (24.5 mg, 0.030 mmol), K3PO4 (127.2 mg, 0.60 mmol), sodium acetate (49.2 mg, 0.60 mmol), water (0.5 mL), and acetonitrile (10 mL). After three cycles of vacuum/nitrogen flush, the mixture was heated at 95° C. for 1 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 30:1 dichloromethane/methanol to afford 335c as a brown solid (60 mg, 22%, two steps). MS-ESI: [M+H]+ 598.2.
