A mixture of (4-butoxymethyl-phenyl)-methanol (190 mg, 0.98 mmol) described in Manufacturing Example 33-1-3, triphenylphosphine (310 mg, 1.2 mmol) and carbon tetrachloride (3 mL) was stirred under reflux for 7 hours. The reaction mixture was cooled to room temperature, and concentrated under a reduced pressure. The residue was purified by neutral silica gel column chromatography (ethyl acetate:heptane=1:15) to obtain the title compound (180 mg, 86%).
