The Stille coupling of 9-{2-[bis(2-propoxy)phosphonylmethoxy]ethyl}-6-chloropurines with 1-(ethoxyvinyl)tributyltin afforded 6-(1-ethoxyvinyl)purine derivatives. Their acid hydrolysis gave 6-acetylpurine derivatives that after reductive amination using various primary and secondary amine hydrochlorides and sodium cyanoborohydride followed by deprotection afforded the title N-substituted 6-(1-aminoethyl)-9-(2-phosphonomethoxyethyl)purine derivatives.
