Reaction Conditions

Reaction Steps

To a solution of 2-(4-Phenoxy-phenoxy)-ethanol (2.2 g, 9.55 mmol), triphenylphosphine (2.76 g, 10.5 mmol), and dichloromethane (DCM) (36.7 mL) after stirring at 0° C., was added N-Bromosuccinimide (1.87 g, 10.5 mmol). The resulting mixture was stirred at 0° C. for 30 minutes and then at room temperature for 30 minutes. Reaction mixture was concentrated in vacuo to obtain the crude mixture, which was purified by of silica gel flash chromatography, using EtOAc/hexane (gradient system), to obtain the product (2.5 g, 89%): 1H NMR (400 MHz, CDCL3).
