Reaction Steps

4-O-(2,3,4,6-tetra-O-acetyl-α-D-galactopyranosyl)-2,3,6-tri-O-acetyl-β-D-glucopyranosyl azide (178 mg, 0.26 mmol) was dissolved in MeOH (5 ml) and hydrogenated over Pd/C (10%) (10 mg) for 5 h. The suspension was filtered, and the filtrate was evaporated to give 4-O-(2,3,4,6-tetra-O-acetyl-α-D-galacto-pyranosyl)-2,3,6-tri-O-acetyl-β-D-glucopyranosyl amine (26) (157 mg, 92%).
