Versuchsvorschrift

2-Chloroethyl-p-toluenesulphonate (6.0 g) was added to a mixture of anthrone (5 g) and potassium carbonate (5 g) in dimethylformamide (130 ml). After stirring for 24 hours at 70° C., the reaction mixture was added to ether. The resultant solution was washed with dilute aqueous potassium hydroxide, dried with magnesium sulphate, and evaporated to yield a crude product which was chromatographed on silica gel, eluting with 4:1 hexane:ethyl acetate, to give 2-(9-anthryloxy)ethyl chloride.
