Abstract: Reaction of bis(2-chloroethyl) ether (II) with triethyl phosphite afforded diethyl 2-chloroethoxyethylphosphonate (III). This compound reacts with sodium salts of heterocyclic bases to give diethyl esters of N-(2-(2-phosphonylethoxy)ethyl) derivatives of purine and pyrimidine bases IV. Compounds IV on reaction with bromotrimethylsilane and subsequent hydrolysis were converted into N-(2-(phosphonylethoxy)ethyl) derivatives IV.
