Procedure

2.2 g of DCC are added, at 0° C., to a stirred solution of 4.31 g (10 mmol) of Fmoc-Cys(StBu)--OH, 7.74 g of H-Arg-Phe-OtBu.2 HClO4 (oily substance obtained above), 1.35 g of HOBt and 1.3 ml of N-ethylmorpholine in 40 ml of dimethylformamide. The mixture is worked up in analogy to Example 1a. The residue is triturated with diethyl ether and dried.
