Reaction Steps

(4-(Benzhydryloxy)phenyl)methanol (500 mg, 1.72 mmol) was dissolved in toluene (20 ml) and pyridine (139 uL, 1.72 mmol) was added. The solution was cooled to 0° C. PBr3 (163 uL, 1.72 mmol) was added dropwise over 15 min. The resulting mixture was stirred at room temperature for 1 h. It was then washed with saturated K2CO3 solution and extracted with EtOAc (3×30 mL). The EtOAc layer was washed with brine and dried (MgSO4). The solvent was evaporated off in-vacuo to obtain ((4-(bromomethyl)phenoxy)methylene)dibenzene as an oil, (450 mg, 74%). This intermediate was used in the following reaction.
