Reaction Steps

Sodium (89 mg) was reacted in dry MeOH (50 mL) then a solution of methyl 2-azido-4-O-biphenylcarbonyl-6-O-tert-butyldiphenylsilyl-2-deoxy-3-O-(4-methoxybenzyl)-1-thio-β-D-glucopyranoside (11) (3 g, 3.88 mmol) in THF (25 mL) was added. The reaction mixture was stirred at 40° C. for 30 minutes, then cooled to room temperature. The solution was neutralized by Amberlite IR 120 (H+) ion exchange resin. The suspension was filtered, the filtrate was evaporated. The residue was purified by chromatography using EtOAc—hexane 1:4 as the mobile phase to give methyl 2-azido-6-O-tert-butyldiphenylsilyl-2-deoxy-3-O-(4-methoxybenzyl)-1-thio-β-D-glucopyranoside (10) (2.1 g, 91%)
