Versuchsvorschrift
0.94 Gram (1.11 mmol) of the ester obtained as described above was dissolved in ethanol (100 ml) and methanol (20 ml), and 0.40 g of 10% palladium-carbon and 0.50 g (4.93 mmol) of 36% hydrogen chloride-ethanol were added. The mixture was stirred in a stream of hydrogen under normal pressure for 2 hours at room temperature. The catalyst was filtered off and the filtrate was concentrated under reduced pressure. The residue was washed with ether (20 ml) to obtain 0.71 g (99%) of the desired 5'-O-{N-(N-lysylalanyl)isoleucyl}-5-fluorouridine dihydrochloride as a colorless powdery solid.
