Procedure

6.5 g of the compound obtained in Step D and 0.3 g of Pd/C (5%) are heated for 40 minutes at 220-240° C. under nitrogen, and then 0.3 g of Pd/C is added again and the reaction is continued for 50 minutes. After returning to ambient temperature, taking up in ethanol, filtration over Celite and concentration under reduced pressure, chromatography of the residue on silica gel (dichloromethane/methanol: 95/5) enables the expected product to be isolated.
