Procedure

A suspension of 4-iodophenol (20 g), 1-bromo-3-chloropropane (18 mL), and potassium carbonate (38 g) in acetone (250 mL) was heated at reflux for 16 h and allowed to cool to room temperature. The suspension was filtered, and the filtrate was evaporated in vacuo. Kugelrohr distillation of the residue (5–10 mm Hg, 210° C.) gave the title compound as a white crystalline solid (22 g).
