实验过程

0.959 g (2.0 mmole) of the 2HCl.H-Pro-Arg-CHA was dissolved in 8 ml of 0.75 N NEM/DMF, to which was added 0.863 g (2.0 mmole) of BOC-D-Thr(OBzl)-SDP at 0°-5° C., and the reaction was effected at room temperature for 18 hours, after which the reaction mixture was poured into 2000 ml of cold 1/1 solution of 10% citric acid/sat. aqueous Nacl. The precipitate was filtered out and dried, to obtain 1.07 g (72.7%) of BOC-D-Thr(OBzl)-Pro-Arg-CHA.
