실험 절차

Ethyl (5S)-12-[(R)-[(2R,3R,4R,5R)-3,4-bis(acetyloxy)-5-(2,4-dioxo-3,4-dihydro-1(2H)-pyrimidinyl)tetrahydro-2-furanyl](hydroxy)methyl]-5-[(1S)-1-hydroxy-2-methylpropyl]-3,6-dioxo-1-phenyl-2-oxa-4,7,11-triazatridecan-13-oate (obtained from Example 36) was hydrogenated using 10% palladium on carbon in absolute methanol under atmospheric pressure, to give ethyl (3R)-2-[(3-{[(2S,3S)-2-amino-3-hydroxy-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]-3-hydroxypropanoate as a white amorphous solid [MS (ES) 616.1 (M+H)].
