실험 절차

196 mg (0.492 mmol) of the compound from example 7A were initially charged in pyridine (22 ml), 74 mg of palladium on carbon (10% by weight) were then added and the mixture was hydrogenated at standard hydrogen pressure overnight. The reaction mixture was then filtered through kieselguhr, the filter cake was washed with ethanol and the filtrate was concentrated. The residue was triturated with ethanol at 50° C., and the solid was filtered off and dried under high vacuum. This gave 107 mg (58% of theory) of the title compound.
