Procedure

The title compound was prepared from solid phase bound Nα-isobutyl-Nα-(4-nitrobenzenesulfonyl)-Nε-(9-fluorenylmethoxycarbonyl)-L-lysine (step A) as described in general procedure Bb using Nα-(4-acetamidobenzenesulfonyl)-L-phenylalanine (400 mg, 1.2 mmol) which was prepared in step A of example 3. The final product was purified by preparative HPLC to yield 55 mg (60%) of the desired material.
