実験手順
To a solution of (S)-2-(2-hydroxy-1-phenylethyl)isoindoline-1,3-dione (1.5 g, 5.61 mmol) in PhCF3 (18.71 mL) was added triethylamine trihydrofluoride (5.48 mL, 33.7 mmol), perfluorobutanesulfonyl fluoride (1.019 mL, 5.67 mmol), DIEA (14.70 mL, 84 mmol) at room temperature. The reaction mixture was stirred at room temperature for 1 h, then more perfluorobutanesulfonyl fluoride (1.019 mL, 5.67 mmol) was added. After 5 h, the reaction mixture was quenched with NaHCO3 and extracted with EtOAc. The combined organic layers were washed with water and brine, dried over anhydrous sodium sulfate, filtered off, and concentrated in vacuo. The crude product was purified by flash chromatography (0-10% EtOAC in heptane) yielding (S)-2-(2-fluoro-1-phenylethyl)isoindoline-1,3-dione (30% yield). LCMS (m/z): 270.1 (MH+), 0.96 min.
