Procedure
In a manner analogous to that described in Example 1, using as starting materials 56 mg of Z-Phe-His-OH, 60 mg of H-Leu-Val-Ala-Sta-OCH3.HCl, 18 mg of HOBT, 0.24 ml of ethyldiisopropylamine and 34 mg of DCCI, the title compound is obtained in the form of a colourless powder after flash chromatography (30 g of silica gel 60, 40-63 μm, system N8). Rf (N9)=0.33.
