실험 절차

Sodium azide (3.11 g, 47.8 mmol) and 2-bromo-6-(bromomethyl)pyridine (Example 190, Step 1) (4.00 g, 15.94 mmol) were combined in DMSO (30 mL) and stirred at room temperature for 4 h. The mixture was subsequently diluted with water and extracted with Et2O (2×). The combined organic extracts were washed with brine, dried (MgSO4), filtered, and evaporated under reduced pressure. The residue was purified by flash chromatography (0-10% EtOAc/hexanes) to yield the title compound as a colorless oil.
