실험 절차

39 g of the product of Example 29 were dissolved in 2000 ml of tetrahydrofuran, and 20 g of catalyst (palladium-on-charcoal, 5% by weight) were added. The reaction mixture was hydrogenated with hydrogen at 25 to 30 bar for 13 hours at room temperature. It was then filtered and the solvent was stripped off under vacuum to leave a solid. The yield was 274 g (=96% of theory). 19F NMR: -61.2 and -86.6 ppm. 1H NMR: 3.02 ppm.
