7-Methyl-1-(β-D-erythro-pento­furan­osyl)-1H-benzimidazol-2(3H)-one

The title nucleoside, C₁₃H₁₆N₂O₅, was prepared and characterized by X-ray crystallographic tech­niques. The crystal structure determination reveals that the furan­ose ring adopts a C2′-endo conformation, while the orientation of the benz­imidazole moiety with respect to the sugar moiety is mid-anti. The crystal structure is stabilized by intermolecular O—H...O and N—H...O hydrogen bonds.
