Reaction Steps

To a solution of (3,5-dimethylpyridin-4-yl)methanol (2.55 g, 18.6 mmol) in anhydrous dichloromethane (130 mL) was added tribromophosphane (2.0 mL, 21.1 mmol). The mixture was stirred at room temperature for 5 hours. Dichloromethane was evaporated. The residue was dried in vacuo, affording 4-(bromomethyl)-3,5-dimethylpyridine. The crude product was used without further purification.
