A mixture of 17.5 g 2-naphthol, 32.0 g of 1-chloro-8-(p-toluenesulphonyloxy)octane, 32.0 g of anhydrous potassium carbonate and 200 ml of DMF was stirred at 60° for 4 hours. Water and ether were then added, the ethereal solution was separated, and washed with water and dilute aqueous potassium hydroxide, then dried and evaporated. The residue was chromatographed on silica gel, eluting with 3:2 hexane: dichloromethane, to afford the title compound as a solid, mp 35°.
