A mixture of 20 g (72.4 mmol) of 2-fluorotetracene-5,12-dione, 94.3 g of octan-1-ol, 30.01 g (217.2 mmol) of anhydrous potassium carbonate and 200 ml of dimethyl sulfoxide is stirred for 20 hours at 100° C. The reaction mixture is cooled, and extracted with toluene/dilute hydrochloric acid. The organic phase is separated, washed with water, dried over sodium sulfate, and concentrated by evaporation. The residue is washed with pentane and recrystallised from cyclohexane. Yield: 22.9 g (82%), m.p. 127°-129° C.
