Reaktionsschritte

To a stirred solution of nucleoside 4 (9.00 g, 0.014 mol) in methanol (130 cm3) was added sodium methoxide (3.87 g, 0.0716 mol). The reaction mixture was stirred at room temperature for 4 h and then neutralised with dilute hydrochloric acid. The mixture was evaporated to dryness under reduced pressure followed by coevaporation using toluene (15 cm3×3). The residue was purified by silica gel column chromatography using dichloromethane/methanol (4–1 5% methanol, v/v) as eluent to give nucleoside triol 5 (4.82 g, 89%) as a white solid material after evaporation of the solvents under reduced pressure.
