PROCEDURE

实验过程

At 0° C. the solution of 1160 mg (1.26 mmol) of HCl.Arg(Tos)-Pro-Ala-Lys(ClZ)-OBzl (SEQ ID NO: 12) in 50 ml of anhydrous tetrahydrofuran was adjusted to pH 9, to which the pre-cold solution of 500 mg (1.41 mmol) of Boc-Asn-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 800 mg (57%) of the title compound as a glassy mass. Mp 86–88° C., FAB-MS (m/e) 1097[M+H]+.
