実験手順

To a solution of (3,5-diethylpyridin-4-yl)methanol (1.50 g, 9.07 mmol) in anhydrous chloroform (40 mL) at 0° C. was added dropwise tribromophosphane (2.48 g, 0.861 mL, 9.16 mmol). The reaction mixture was allowed to stir overnight at room temperature. The solvent was evaporated to provide crude 4-(bromomethyl)-3,5-diethylpyridine, which was used for the next step without any further purification; M+229.2.
