Human SDF‐1α contains 68 amino acids and is a member of the chemokine family of peptides. This long peptide was synthesized stepwise using classical conditions in 101 h. The reaction times were then reduced to deprotection times of 2 × 2 min and coupling times of 2 × 2.5 min, resulting in a total synthesis time of 22 h. The effect of different resins, resin substitutions and deprotection reagents on the crude peptide purities was compared. A small portion of crude peptide was purified using an RP‐HPLC column and the mass of the final product was confirmed with MALDI‐TOF mass spectrometry.
