      Abstract:

      Oligomers of arginine, such as octa-D-arginine amide, are   excellent transporters for active drugs through cell membranes   and tissue. The synthesis of octa-D-arginine amide, as the   nonahydrochloride salt, was approached via a solution phase   synthetic route involving guanidinylation step. The multi-step   synthesis was carried out at pilot scale, resulting in the   preparation of 700 g of the target molecule. No chomatographic   purification was needed at any step of the process.
