الإجراء التجريبي

Ethyl (5S)-12-{(R)-(acetyloxy)[(2R,3R,4R,5R)-3,4-bis(acetyloxy)-5-(2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)tetrahydro-2-furanyl]methyl}-5-isobutyl-3,6-dioxo-1-phenyl-2-oxa-4,7,11-triazatridecan-13-oate (97 mg, 0.125 mmole, obtained from Example 38) was hydrogenated using 10% palladium on carbon in methanol (2 ml) under atmospheric pressure. The catalyst was removed and the volatiles were removed in vacuo to provide ethyl (3R)-3-(acetyloxy)-2-[(3-{[(2S)-2-amino-4-methylpentanoyl]amino}propyl)amino]-3-[(2R,3R,4R,5R)-3,4-bis(acetyloxy)-5-(2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)tetrahydro-2-furanyl]propanoate (76 mg, 95%) as a white glassy solid.
