실험 절차
The title compound was prepared from Nα-isobutyl-Nα-(4-methylbenzenesulfonyl)-L-lysine (100 mg, 0.29 mmol, example 1, step E) as described in general procedure Bc using Nα-(4-nitrobenzenesulfonyl)-L-tryptophan (120 mg, 0.3 mmol) which was prepared in step A of example 5. The final product was purified by HPLC to give 66 mg (36%) of pure adduct.
