PROCEDURE

实验过程

The title compound was prepared from Nα-isobutyl-Nα-(4-nitrobenzenesulfonyl)-L-lysine hydrochloride (400 mg, 1.03 mmol, example 5, step C) as described in general procedure Bc using Nα-(2-thiophenesulfonyl)-L-phenylalanine (311 mg, 1.2 mmol) which was prepared in step A of example 24. The final product was purified by preparative HPLC to yield 550 mg (80%) of Nα-isobutyl-Nα-(4-nitrobenzenesulfonyl)-Nε-[N′α-(2-thiophenesulfonyl)-L-phenylalanyl]-L-lysine. The latter derivative was hydrogenolysed following the indications of general procedure E. Purification by HPLC gave the desired material (400 mg, 65%).
