3-Deoxy-3-(p-fluorine-phenylamino)-1,2-O-isopropylidene-α-D-ribofuranose 3 was synthesized and characterized by IR, NMR and HRMS, and its crystal structure was determined by X-ray diffraction analysis. Crystal data for 3: monoclinic, space group P21, a = 7.0403(14), b = 6.7780(4), c = 14.932(3) A, β = 94.74(3)°, C14H18FNO4, Mr = 283.29, V = 710.1(2) ·3, Z = 2, Dc = 1.325 g/cm3, μ = 0.105 mm-1, F(000) = 300, the final R = 0.0468 and wR = 0.0926 for 1969 observed reflections (I > 2σ(I)). Two intermolecular hydrogen bonds are observed. The absolute configuration of this molecule was confirmed by comparison with that of the original material.
