실험 절차

To a methanol solution (4 mL) of (1S)-1,5-anhydro-2,3,4,6-tetra-O-benzyl-1-[2-(benzyloxy)-5-[4-[2-[[[(2-hydroxy-1,1-dimethylethyl)amino]carbonyl]amino]ethyl]benzyl]-4-methylphenyl]-D-glucitol (0.184 mg, 0.190 mmol) was added 20% palladium hydroxide (0.180 g), and the mixture was stirred under a hydrogen atmosphere at room temperature overnight. The reaction solution was filtered through celite and evaporated under reduced pressure. Thus obtained residue was purified with silica gel column chromatography (chloroform:methanol=17:3) to obtain the title compound (57 mg, 58%) as a colorless powder. NMR data and MS data of the compound are shown in Table 1.
