Vorschrift

Phosphorous tribromide (2 mL) was added to a solution of (4-benzyloxy-3-chlorophenyl)-methanol (CAB02127, 3.40 g, 13.7 mmol) in dichloromethane (50 mL) at 0° C. The mixture was stirred at this temperature for 1 h, diluted with diethyl ether (100 mL), transferred into a separation funnel and washed with water (50 mL) and brine (50 mL). The organic layer was dried over magnesium sulphate and concentrated under reduced pressure to give a white, analytical pure solid. Yield: 4.27 g (100%).
