3-(4-Propylphenyl)bromopropane (s4) (14.0 g), toluene (100 ml) and triphenylphosphine (31.5 g) were placed in a reaction vessel under an atmosphere of nitrogen, and the mixture was heated to reflux for 5 hours. After the reaction mixture had been cooled to 25° C., the deposits were filtered, and the unreacted material was removed by washing with toluene three times. The resulting colorless solids were dried to give 3-(4-propylphenyl)propyltriphenyl phosphonium bromide (s5) (30.0 g). The yield based on the compound (s4) was 99.1%.
