Procedure

339 g of the product of Example 17a were dissolved in 2000 ml of tetrahydrofuran and treated with 20 g of catalyst (palladium on charcoal, 5% strength by weight). The mixture was hydrogenated with hydrogen for 13 hours at 25 to 30 bar and at room temperature. The batch was then filtered and the solvent was stripped off in vacuo. A solid remained. The yield was 274 g (=96% of theory). 19F-NMR: -61.2 and -86.6 ppm. 1H-NMR: 3.02 ppm.
