A new method for the synthesis of title compound has been reported: The reaction of 5'-O-triphenylmethyl-2'-deoxyadenosine (I) with CS2, methyl iodide and NaH gives the corresponding xanthate (II), which is reduced with tributyl hydrogen stannide to 5'-O-triphenylmethyl-2',3'-dideoxyadenosine (III). Finally, this compound is deprotected in the usual way.
