실험 절차

H-Leu-Arg(Tos)-Pro-NHEt was dissolved in 80 mL of DMF and 200 mL of THF. With cooling the solution was neutralized with N-methylmorpholine. To the solution, a solution in which 8.86 g of Boc-D-Leu-OH and 23.02 g of HOSu were dissolved in 200 mL of THF, and 36.4 mL of WSC were added. Next the mixture was stirred at 0° C. for 5 minutes and at room temperature overnight. After confirmation with ninhidrin, the reaction mixture was concentrated under reduced pressure. To the residue, 500 mL of water was added, then the mixture was extracted 5 times with 200 mL of n-butanol and washed five times with water. The n-butanol layer was concentrated under reduced pressure, then the residue was solidified by treatment with ether. Thus 21.5 g of Boc-D-Leu-Leu-Arg(Tos)-Pro-NHEt (92.1% yield) was obtained.
