Phosphorus tribromide → 2-Benzyloxy-6-bromomethyl-naphthalen

Participants

Reaction Steps

To a solution of (6-benzyloxy-naphthalen-2-yl)-methanol (17) (1 equi.) in CH2Cl2 (4 mL/mmole), a solution of phosphorus tribromide (4 mL/mmole), (0.4 equi.) was added at room temperature. The reaction mixture was stirred at that temperature for 24 h, quenched with water, extracted with dichloromethane, washed with brine, dried over MgSO4, and concentrated in vacuo. Purification by chromatography on silica gel (dichloromethane) and recrystallization from acetonitrile afforded 2-benzyloxy-6-bromomethyl-naphthalene (18) a white solid (92%).
