実験手順

By methods substantially equivalent to those described in Examples 1-A, 1-B, 7-A, 1-D, 1-H and 1-I, using ethyl chloroformate in place of MeSO2Cl and using Boc-D-Cha-OH in place of Boc-D-Phe-OH, 0.6 g of EtOCO-D-Cha-Pro-Arg-H.HCl hydrate was prepared. EtOCO-D-Cha-Pro-Arg-H.HCl was purified by RPHPLC (95/5 (A/B) ramp to 60/40 (A/B), 240 min).
