Versuchsvorschrift

520 mg (1.73 mmol) of the compound from Example 46A are dissolved in 10 ml of THF. 30 mg of palladium on carbon are added, and the mixture is hydrogenated at RT in a hydrogen atmosphere under atmospheric pressure. The mixture is then filtered through kieselguhr, the filter cake is washed three times with THF and the filtrate is freed from the solvent. The reaction product is reacted further without further purification. This gives 471 mg (89% of theory) of the desired product.
