A series of peptides related to some of the autophosphorylation sites of the epidermal growth factor receptor has been synthesized on solid phase, using side-chain-unprotected phosphotyrosine. Although the desired peptides could be obtained, this approach was not entirely satisfactory due to a side

✦ Synopsis
In order to minimise the formation of the pyrophosphate derivative of the target peptide when side-chainunprotected phopshotyrosine is used in solid-phase peptide synthesis, this building block can be incorporated using benzotriazolyloxy-tris-(dimethylamino)phosphonium hexafluorophosphate/1-hydroxybenzotriazole/N-methylmorpholine (1:1:2.3) in the presence of a chaotropic salt (0.4 M LiCI in N-methyl-2-pyrrolidinone).
