Procedure

1.8 g (11 mmol) of diethylaminosulfur trifluoride (DAST) were added to 3.0 g (10 mmol) of the alcohol from Example 1 in 50 ml of dichloromethane at -50° C., and the mixture was stirred at room temperature for 1 hour. It was poured into water and the organic phase was washed with aqueous sodium hydrogen carbonate solution, dried and concentrated. The crude product was chromatographed on silica gel with petroleum ether/ethyl acetate 7:3 to give, first of all, 0.8 g (28.6% of theory) of the product indicated above as a colorless oil, and then 1.5 g (50.5% of theory) of the fluorination product described in Example 6, as a colorless oil (see Example 6).
