反応手順

1-(6-Bromopyridin-2-yl)prop-2-yn-1-ol (1.06 g, 5.00 mmol) was dissolved in CH2Cl2 (20 mL) and cooled to 0° C. Diethylaminosulfur trifluoride (925 μL, 7.00 mmol) was added dropwise, and the brown solution was stirred at 0° C. for 1 h. The reaction was quenched with saturated NaHCO3 and extracted with CH2Cl2 (3×). The combined organic layers were washed with brine, dried (MgSO4), filtered, and evaporated. Flash chromatography (0-15% EtOAc/hexanes) afforded the title compound as an orange oil.
