A two phase mixture of phenol (5 g, 53 mmol), 1,4-dichlorobutane (30 ml), tetrabutylammonium hydrogen sulphate (0.3 g, 1 mmol), and sodium hydroxide solution (25 ml, 6M) was refluxed for 3 h. The organic layer was separated, dried (MgSO4), and concentrated in vacuo. The residues were purified by flash chromatography (silica (Merck 15111); eluant:petrol) to give the product as a colourless viscous oil (7.57 g 77%) bp 250° C. at 0.2 mm Hg.
