ABSTRACT:
A process for the solid phase synthesis of a peptide having at least one thyptophan residue, wherein said method comprises temporarily protecting the indole ring of said tryptophan residue with a side chain protecting group which is labile to a base wherein said protecting group is removed during cleavage of said peptide from the solid support.
