A series of novel 2-(benzylamino)-6-oxopurine derivatives has been synthesized by arylalkylation of the corresponding 2-(acetylamino)-6-(diphenylcarbamoyloxy)purines. The decisive role of the temporary O6-(diphenylcarbamoyl) protection on the benzylation of the exocyclic amino group in 2-(acetylamino)-6-oxopurines has been demonstrated.
