Reaction Steps

To a solution of (2-benzyloxy-5-bromo-phenyl)-methanol (4.36 g, 14.87 mmol) in DCM (200 ml) cooled with ice-bath under N2 atmosphere a 1M solution of PBr3 in DCM (14.87 ml, 14.87 mmol) was added. The mixture was stirred at that temperature for 15 min and then at RT overnight. The reaction was quenched with sat. NaHCO3 solution. The organic layer was separated, washed with brine, dried (MgSO4) and evaporated to dryness.
