Reaction Steps

Palladium catalyst (10% on carbon, 20.0 mg) was added in one portion to a solution of 2,3,4,6-tetra-O-acetyl-β-D-galacto-pyranosyl azide (6)(500 mg, 1.34 mmol) in abs. methanol (5 ml) under a hydrogen atmosphere. A small amount of abs. THF was added to dissolve the sugar. The solution was allowed to stir for 12 hours. The catalyst was subsequently filtered off, and the solvent evaporated. Purification by column chromatography gave (11) (400 mg, 86%).
