Reaction Steps

To a solution of benzyl (2-{[2,3,4,6-tetra-O-benzoyl-α-D-mannopyranosyl-(1→3)-[2,3,4,6-tetra-O-benzoyl-α-D-mannopyranosyl-(1→6)]-2-O-benzoyl-4-O-benzyl-β-D-glucopyranosyl]oxy}ethyl)carbamate (3.39 g, 1.984 mmol) in CH3OH (30 mL) was added NaOCH3 (0.4 mL, 0.2 mmol, 0.5 M in CH3OH). After stirring at rt for 24 hr, amberlite IR 120 (H) ion exchange resin (pre-washed with CH3OH 3×30 mL) was added to the reaction mixture. The resulting mixture was allowed to stir for additional 15 min. The resin was filtered off and washed with CH3OH (3×5 mL). The filtrate was concentrated to give the title compound. UPLC Method B: calculated for C35H49NO18 771.29, observed m/e: 772.42 [M+1]; Rt=2.51 min.
