Versuchsvorschrift

To a solution of 2-bromo-6-(fluoro{1-[(trimethylsilyl)methyl]-1H-1,2,3-triazol-4-yl}methyl)pyridine (500 mg, 1.46 mmol) in THF (10 mL) was added TBAF (1.0 M in THF, 4.37 mL, 4.37 mmol). The reaction was stirred at room temperature for 2 h. It was then diluted with water and extracted with EtOAc (2×). The combined organic layers were washed with brine, dried (MgSO4), filtered, and evaporated. Flash chromatography (30-100% EtOAc/hexanes) provided the title compound as a colorless solid.
