Pyridine → Fmoc-phenylalanine fluoride

참여 물질

반응 단계

FMOC-L-Phenylalanine (17 g, 44 mmol) (Bachem) was dissolved in dichloromethane (100 mL). Pyridine (3.55 mL, 44 mmol) (Aldrich) and cyanuric fluoride (6 g, 44 mmol) (Aldrich) were successively added at room temperature and the mixture was stirred for 3.5 hours. Ice cold water (300 mL) was added and the resulting slurry was filtered. The filtrate was poured into a separatory funnel and the layers were separated. The organic layer was dried over anhydrous sodium sulfate, filtered and concentrated under reduced pressure to afford FMOC-L-phenylalanyl fluoride as a white powder. (Yield 13.6 g, 80%).
