The preparation of a nucleotidyl-peptide having a thymidin-5'-yl-(P-O)-serine phosphodiester bond, [HAla-Ser(pTpT)-Phe-OH](24) is described. After condensation between the phosphorylated peptide component and an oligonucleotide component, all protecting groups could be removed under neutral conditions without ^-elimination of the pTpT from the serine moiety.
