Reaction Steps
A mixture of (4-(benzyloxy)phenyl)methanol (2.14 g) and lithium bromide (1.0 g) in N,N-dimethylformamide (20 mL) was cooled to 0° C. To this solution was added PBr3 (1.0 mL). The solution was stirred at room temperature for 2 hours. The reaction mixture was partitioned between water and ethyl acetate. The aqueous layer was extracted with additional ethyl acetate, twice. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by flash column chromatography on silica gel eluting with 5% ethyl acetate in hexanes to provide the title compound.
