Procedure

To a stirred solution of methyl 3-(3-hydroxypropyl)phenoxyacetate (2.00 g) in methylene chloride (20 ml) were added successively triphenylphosphine (2.81 g) and tetrabromomethane (3.55 g) at room temperature. The mixture was evaporated. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=7:1) to give the title compound (1.69 g) having the following physical data.
