実験手順
A solution of 4-(2-fluoro-5-bromobenzyloxy)butanol (7.03 g, 26.3 mmol) in diethyl ether (88 ml) was treated with triphenylphosphine (8.97 g, 34.2 mmol) and carbon tetrabromide (11.3 g, 34.2 mmol). The cloudy solution was stirred at ambient temperature for about 30 hours. The precipitate was removed by filtration and the filtrate was concentrated. The desired title intermediate was purified from the filtrate by bulb to bulb distillation.
