A solution of 0.85 g (7.42 mmol) of methanesulphonyl chloride in 5 ml of dichloromethane is added dropwise to a solution, cooled with an ice bath, of 1.2 g (5.71 mmol) of 5-(naphth-1-yl)pent-4-yn-1-ol, obtained in stage 3.1., and of 1.6 ml (11.4 mmol) of triethylamine in 12 ml of dichloromethane. The mixture is stirred at 0° C. for 1 hour and then at ambient temperature for 2 hours. 25 ml of water and 75 ml of dichloromethane are subsequently added. The organic phase is separated by settling and is washed with 25 ml of water and then with 25 ml of a saturated aqueous sodium chloride solution. It is dried over magnesium sulphate and evaporated to dryness to produce 1.68 g of product in the form of an orange oil used directly in the following stage.
