A solution of 11.8 grams (0.05 mole) of 4-fluoro-3-phenoxyphenylmethyl chloride (prepared in Example 2, Step B) and 13.1 grams (0.05 mole) of triphenylphosphine in 150 mL of dry tetrahydrofuran was stirred for about 60 hours. After this time the reaction mixture was concentrated under reduced pressure to a solid residue. The solid was stirred with diethyl ether and was collected by filtration, yielding 15 grams of (4-fluoro-3-phenoxyphenyl)methyltriphenylphosphonium chloride.
