Versuchsvorschrift

By using an analogous procedure to that described in Example 2, tert-butyl (5S,12S)-12-[(S)-[(3R,4R,5R)-3,4-bis{[tert-butyl(dimethyl)silyl]oxy}-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 (77 mg, 0.076 mmol, obtained from Example 8) was hydrogenated in methanol (2 ml) using 10% palladium on carbon (15 mg). The product was purified by chromatography (flash column, silica gel, 10 methanol in methylene chloride) to provide tert-butyl (2S,3S)-2-[(3-{[(2S,3S)-2-amino-3-hydroxybutanoyl]amino}propyl)amino]-3-[(3R,4R,5R)-3,4-bis{[tert-butyl(dimethyl)silyl]oxy}-5-(3-(4-methoxybenzyl)-2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)tetrahydro-2-furanyl]-3-hydroxypropanoate (20 mg, 30%) as a pale yellow solid.
