An Nα-protected-NG-protected-arginyl-p-nitroanilide with high purity can be produced in high yield by reacting an Nα-protected-NG-protected-arginine with p-nitroaniline in pyridine in the presence of a condensing agent.

Common protecting groups used in amino acid/peptide chemistry were all well-tolerated. The method was also successfully applied to the synthesis of a dipeptide conjugate, indicating that the methodology is applicable to the synthesis of chromogenic substrates containing short peptides. The method has general applicability to the synthesis of chromogenic and fluorogenic peptide substrates and represents
