Procedure

A mixture of 8.89 g (44.0 mmol) of triphenylphosphine and 11.2 g (42.7 mmol) methyl 4-methoxybenzenesulfonate was allowed to react for 2 hr at 140° C. A total of 18.0 g (38.7 mmol, 90.7%) of the title compound was obtained. It was further purified by recrystallization from 90:10 tolueneacetonitrile. Analyses: mp 96.0°-98.5° C.;
