The present invention is directed to the process for the preparation of 2′-deoxy-2′-halo-&bgr;-L-arabinofuranosyl nucleosides, and in particular, 2′-deoxy-2′-fluoro-&bgr;-L-arabinofuranosyl thymine (L-FMAU), from L-arabinose, which is commercially available and less expensive than L-ribose or L-xylose, in ten steps. All of the reagents and starting materials are inexpensive and no special equipment is required to carry out the reactions.
