反応手順

2-Bromo-6-(1-fluoroprop-2-yn-1-yl)pyridine (520 mg, 2.43 mmol) and trimethylsilylmethyl azide (377 mg, 2.92 mmol) were combined in t-BuOH (5.0 mL) and water (3.0 mL). CuSO4.5H2O (30 mg, 0.12 mmol) in water (1.0 mL) was added, followed by sodium ascorbate (96 mg, 0.49 mmol) in water (1.0 mL). The reaction was stirred at room temperature overnight, diluted with saturated NaHCO3, and extracted with EtOAc (2×). The combined organic layers were washed with brine, dried (MgSO4), filtered, and evaporated to a brown residue that was purified by flash chromatography (0-30% EtOAc/hexanes) to afford the title compound as a colorless solid.
