실험 절차

In a manner analogous to that described in Example 1, using as starting materials 221 mg of Z-Phe-His-OH, 150 mg of H-Leu-Val-3-(2-pyrrolidinon-1-yl)-propyl amide, 77 mg of HOBt and 122 mg of DCCI, the title compound is obtained after flash chromatography (65 g of silica gel 60, 40-63 μm, eluant system B7). Rf (B7)=0.26, Rf (N12)=0.34.
