| Reactant | Phosphorus tribromide | HCID 24614 | — |
| Reactant | (2-Ethylpyridin-3-yl)methanol | HCID 19690951 | — |
| Solvent | Dichloromethane | HCID 6344 | — |
| Product | 3-(Bromomethyl)-2-ethylpyridine | HCID 59589410 | — |
Reaction Steps
To a solution (2-ethylpyridin-3-yl)methanol (3.0 g, 21.9 mmol) in anhydrous dichloromethane (150 mL) was added tribromophosphane (2.3 mL, 24.2 mmol). The mixture was stirred at room temperature overnight. Dichloromethane was evaporated. The residue was dried in vacuo, affording 3-(bromomethyl)-2-ethylpyridine, which was used without further purification.
