Reaction Steps

4-O-α-D-glucopyranosyl-β-D-glucopyranosyl bromide, heptaacetate (4) is reacted with sodium azide in dimethylsulfoxide at 55°-65° C. for 10-30 minutes followed by extraction in organic solvents, giving 4-O-α-D-glucopyranosyl-β-D-glucopyranosylazide, heptaacetate (6). The azide is hydrogenated at room temperature under pressure in dioxane-triethylamine solution using 10% palladium on carbon catalyst. The product is crystallized from dioxane-ethanol to provide 4-O-α-D-glucopyranosyl-β-D-glucopyranosylamine, heptaacetate (heptaester).
