2 g (5.8 mmol) of 4-[3-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthyl)-1-propynyl]benzoic acid, 30 ml of DMF, 2 drops of 15-crown-5 and 2 g (23.8 mmol) of sodium bicarbonate are introduced into a round-bottomed flask. 3.1 ml (20.8 mmol) of 1-iodohexane are added and the mixture is stirred at room temperature for 24 hours. The reaction medium is poured into water and extracted with ethyl acetate and the organic phase is separated out after settling has taken place, washed with water, dried over magnesium sulphate and evaporated. 2 g (80%) of the expected hexyl ester are collected in the form of a pale red oil.
