Phosphine, triphenyl-, hydrobromide → {5-Fluoro-2-[2-(4-methoxyphenyl)ethyl]benzyl}triphenylphosphonium bromide

Participants

Reaction Steps

A solution of 5.95 g (22.86 mmol) of {5-fluoro-2-[2-(4-methoxyphenyl)ethyl]phenyl}methanol in 130 ml of acetonitrile is mixed with 7.45 g (21.71 mmol) of triphenylphosphonium bromide and heated under reflux for 3 hours. The reaction solution is then concentrated to dryness, and the resulting oil is triturated in diethyl ether. The product crystallizes as a white solid during this. After filtration, the solid is dried in a drying oven at 50° C. overnight. 11.5 g (77% of theory) of the title compound are obtained.
