Procedure

A mixture of 5.25 g (11.3 mmol) of tris(4-trifluoromethylphenyl)phosphine and 2.43 g (13.0 mmol) of methyl tosylate were allowed to react for 2 hr at 135° C. A total of 5.41 g (8.29 mmol, 73.4%) of product was obtained, which was further purified by recrystallization from toluene-ethanol. Analyses: mp 185.0°-185.8° C.
