Procedimiento

In a manner analogous to that described in Example 1, using as starting materials 54 mg of Z-Phe-Phe-OH(Bachem AG, Bubendorf, Switzerland) and 75 mg of H-Leu-Val-Ile-His-NH2, the title compound is obtained after the addition of 26 mg of HOBt and 42 mg of DCCI and chromatographic purification over a LOBAR® prefabricated column (eluant: methylene chloride/methanol/water 50:10:1). Rf (B10)=0.35.
