Reaktionsschritte

0.2 ml of a solution of sodium methylate in methanol (8% w/v of Na) is added under an inert atmosphere to a suspension of 1.1 g (2.6.10-3 mol) of 4-nitrophenyl 2,3,4-tri-O-acetyl-5-thio-β-D-xylopyranoside in 30 ml of methanol. After complete solubilization (2 h), the reaction mixture is neutralized by the addition of Amberlite® IR 120 H+ resin and then filtered. 620 mg (yield: 79%) of the expected product are obtained after evaporation to dryness and lyophilization.
