Reaction Steps

The solution of 250 mg (0.330 mmol) of Boc-Ala-Arg(Tos)-Pro-Ala-OBzl (SEQ ID NO: 7), 1 ml of anisole and 2 ml of HF was stirred at 0° C. for 2 h. The reaction mixture was evaporated under reduced pressure to remove HF. To the residue 2 ml of HF were added and the solution was stirred at 0° C. for another 1 h. The reaction mixture was evaporated under reduced pressure to remove HF. The residue was triturated with ether and the resulted solid was purified on the Sephadex G-10 column. The collected fractions were lyophilized to provide 80 mg (58%) of the title compound. Mp. 157–159° C., FAB-MS (m/e) 415[M+H]+.
