The present invention provides a manufacturing process for preparing a peptide, preferably a decapeptide, such as degarelix, by incorporating p-nitro-phenylalanin in the amino acid sequence preferably during stepwise solid phase synthesis, and Converting these into the required amino acids Aph(Hor) and/or D-Aph(Cbm), preferably while attached to a solid phase. The invention further provides intermediates useful in the manufacturing process.
