1.3 g (3.59 mmol) of the compound from Example 9A and 150 mg of platinum on carbon (5%) were dissolved in 150 ml of methanol and hydrogenated at atmospheric pressure for 18 h. For work-up, the catalyst was filtered off through kieselguhr and the filtrate was concentrated on a rotary evaporator. Drying of the residue under high vacuum gave 1.26 g (89% of theory) of the title compound of a purity of 92%.
