HCID 5209941-(Chloromethyl)-4-phenoxybenzeneYield 92%

Procedure

To a solution of (4-phenoxy-phenyl)-methanol (408 mg, 2.04 mmol) in carbon tetrachloride (8.2 mL) was added triphenylphosphine (642 mg, 2.45 mmol) under nitrogen atmosphere at room temperature, and the reaction solution was stirred under reflux for 7 hours and 40 minutes. The reaction mixture was cooled to room temperature and concentrated under a reduced pressure. The residue was purified by silica gel column chromatography (heptane:ethyl acetate=10:1) to obtain the title compound (409 mg, 92%).
