Reaction Steps

To a solution of (5-ethylpyridin-3-yl)methanol (3.31 g, 24.12 mmol) in anhydrous chloroform (50 mL) at 0° C. was added tribromophosphane (7.18 g, 2.49 mL, 26.54 mmol) dropwise. The reaction mixture was allowed to stir overnight at room temperature. The solvent was evaporated to provide crude 3-(bromomethyl)-5-ethylpyridine (4.82 g, 100% yield), which was used in the next step without any further purification.
