Procedure

A mixture of 2.38 g (7.82 mmol) of tris(4-methylphenyl)phosphine and 1.53 g (8.22 mmol) of methyl tosylate were allowed to react for 1 hr at 130° C. A total of 2.38 g (4.85 mmol, 62.0%) of product was obtained, which was further purified by recrystallizatin from 97:3 toluene-ethanol. Analyses: mp 103.4°-137.1° C.
