Versuchsvorschrift

4.19 g of Z-Lys(Boc)-OPc and 2.47 g of HCl.H-Phe-Phe-OH are taken up in 50 ml of dimethylformamide, 0.84 ml of N-ethylmorpholine are added and the whole is left to stand for 24 hours at 20°. The reaction mixture is concentrated by evaporation and the residue is triturated with water and dried over phosphorus pentoxide. Recrystallisation from ether yields crystals having a melting point of 154° to 156°.
