Three approaches to the synthesis of the title (purin-6-yl)methylphosphonates were investigated and compared. While, the Arbuzov reaction of 6-(iodomethyl)purines with triethyl phosphite did not work, Michaelis–Becker alkylation of the sodium salt of diethyl phosphonate with 6-(mesyloxymethyl)purines gave the desired products in good yields. The best method was based on Rh- or Pd-catalyzed cross-coupling reactions of 6-iodopurines with (diisopropoxyphosphorylmethyl)zinc bromide.
