An efficient method for the synthesis of 6-alkyl or 6-aryl purines (nucleosides) was developed via nickel-catalyzed Negishi cross-couplings of 6-chloropurines and organozinc halides. The ligand-free process gave good to excellent isolated yields at room temperature.

The phase transfer method was applied to perform the nucleophilic substitution of 2,6-dichloropurines by modified arylalkyl alcohol or phenols. Since under these conditions only the 6-halogen is exchanged, this method gives 2-chloro-6-aryloxy- and 2-chloro-6-arylalkoxy-purines. 2-Chloro-6-benzylthiopurine was synthesized by alkylation of
