Triphenylphosphine (85.8 g) was added to a Tol (400 ml) solution of methyl 3-bromomethylbenzoate (50.0 g), followed by stirring at 80° C. for 10 hours. After this was cooled to room temperature, the crystal precipitated was collected by filtration and washed with Tol. This was dried under reduced pressure to obtain (3-methoxycarbonylbenzyl)(triphenyl)phosphonium bromide (107.6 g).
