Procedure

Acetic anhydride (25 mL) was added to a solution of methyl-5-azido-2.5-dideoxy-D-ribose (6.2 g, 38 mmol) in pyridine (100 mL). After 4 hours at room temperature, the mixture was concentrated in vacuo. The residue (6 g) was purified by flash chromatography eluting with hexanethylacetate (8:2). Evaporation of the eluting solvent gave the product as an oil (4.9 g, 60% yield). NMR
