The invention discloses a method for the preparation of a peptide by liquid phase coupling of two fragments, an N-terminal fragment and a C-terminal fragment of the desired peptide, wherein the C-terminal fragment is protected on its C-terminal COOH by a psWang linker; the method is demonstrated with liraglutide wherein the C-terminal fragment carries the Palmitoyl-Glu-OtBu residue on the Lys.
