실험 절차

A 50-mL single-neck round-bottomed flask equipped with a magnetic stirrer and a reflux condenser was charged with 317a (100 mg, 0.28 mmol), 4-chloro-2-{4,4-dimethyl-9-oxo-7-thia-10-azatricyclo[6.4.0.02,6]dodeca-1(8),2(6)-dien-10-yl}pyridine-3-carbaldehyde 109a (112 mg, 0.28 mmol), Pd(dppf)Cl2 (22.9 mg, 0.028 mmol), K3PO4 (118.7 mg, 0.56 mmol), sodium acetate (45.9 mg, 0.56 mmol), water (0.5 mL), and acetonitrile (10 mL). After three cycles of vacuum/argon flush, the mixture was heated at reflux for 1 hour. 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 dichloromethane/methanol (50:1 to 30:1) to afford 317b as a yellow solid (60 mg, 36%). MS-ESI: [M+H]+ 597.8.
