Reaction Steps

To a solution of (2-ethyl-phenyl)-methanol (3 g, 22 mmol) in ether (10 mL) at 0° C. was added a solution of PBr3 (2.18 g, 8.1 mmol) in ether (3 mL). The reaction mixture was warmed to r.t for 45 minutes and cooled to 0° C. The reaction mixture was treated with 50% aqueous KOH (15 mL) and separated. The organic layer was dried with KOH pellets and concentrated to give 3.9 g of 1-bromomethyl-2-ethyl-benzene.
