20 mg of palladium on activated carbon (10%) are added to a mixture of 0.127 g (0.19 mmol) of the compound from Example 230A in 10 ml of ethanol, and the mixture is then hydrogenated under atmospheric pressure for 12 h. The reaction mixture is filtered through kieselguhr, and the filtrate is concentrated in vacuo and dried under high vacuum. The crude product is reacted without further purification.
