Vorschrift

tert-Butyl (5S,12S)-12-[(R)-[(3S,4R,5R)-3,4-dihydroxy-5-(3-(4-methoxybenzyl)-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)tetrahydro-2-furanyl]-(hydroxy)methyl]-5-[(1S)-1-hydroxyethyl]-3,6-dioxo-1-phenyl-2-oxa-4,7,11-triazatridecan-13-oate (8 mg, 0.01 mmol, obtained from Example 44) was hydrogenated in methanol (2 ml) using 10% palladium on carbon (5 mg) under atmospheric pressure for 4 hours. The catalyst was removed and the volatiles was concentrated in vacuo to provide tert-butyl (2S,3R)-2-[(3-{[(2S,3S)-2-amino-3-hydroxybutanoyl]amino}propyl)amino]-3-[(3S,4R,5R)-3,4-dihydroxy-5-(3-(4-methoxybenzyl)-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)-tetrahydro-2-furanyl]-3-hydroxypropanoate (6 mg, 92%) as a yellow solid.
