and 4-pyridylmethyl(amino)phosphonicacids at not available by hydrolysis of corresponding phosphonicesters by means of aq. hydrochoric acid. During hydrolysis of these esters a cleavage of C-P bond occurs, which leads to a repulsion of phosphorus moiety and formation of the corresponding amine. It was found, that silylation of pyridylmethyl(amino)phosphonic diethyl esters with bromotrimethylsilane
