실험 절차

At 0° C. the solution of 467 mg (0.51 mmol) of HCl.Arg(Tos)-Pro-Ala-Lys(ClZ)-OBzl (SEQ ID NO: 12) in 20 ml of anhydrous tetrahydrofuran was adjusted to pH 9, to which he pre-cold solution of 195 mg, (0.53 mmol) of Boc-Gln-Onp in 10 ml of anhydrous tetrahydrofuran was added. The reaction mixture was stirred at room temperature for 96 h and TLC (chloroform/methanol, 9:1) indicated complete disappearance of HCl.Arg(Tos)-Pro-Ala-Lys(ClZ)-OBzl (SEQ ID NO: 12). The reaction mixture was evaporated to dryness and the residue was purified on sinica gel chromatography (CHCl3/CH3OH, 10:1) to provide 450 mg (80%) of the title compound as a glassy mass. Mp 80–82° C., FAB-MS (m/e) 1111.3[M+H]+, 1132.5[M+Na]+,1010.0[M-Boc]+.
