Методика

In a manner analogous to that described in Example 1, using as starting materials 69 mg of Z-Phe-Arg-OH, 50 mg of H-Leu-Val-Ile-His-NH2, 16 mg of HOBt and 40 mg of DCCI, the title compound is obtained in the form of a colourless powder after flash chromatography (45 g of silica gel 60, 40-63 μm, eluant system methylene chloride/methanol/water/glacial acetic acid 330:100: 19:2). Rf (S3)=0.16.
