실험 절차

A 100-mL single-neck round-bottomed flask equipped with a magnetic stirrer and reflux condenser was charged with 330h (133 mg, 0.43 mmol), 330c (178 mg, 0.43 mmol), sodium acetate (71 mg, 0.86 mmol), K3PO4 (182 mg, 0.86 mmol), Pd(dppf)Cl2 (35 mg, 0.043 mmol), acetonitrile (15 mL), and water (0.5 mL). After bubbling nitrogen through the resulting mixture for 20 minutes, the reaction mixture was heated at 95° C. for 3 h. After this time the reaction was cooled to room temperature and filtered. The filtrate was concentrated under reduced pressure. The residue was purified with silica-gel column chromatography eluting with 30:1 dichloromethane/methanol to afford 330i as a yellow solid (69 mg, 25%). MS-ESI: [M+H]+ 644.3.
