Reaction Steps
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 commercially available Nα-tert-butoxycarbonyl-L-tryptophan (90 mg, 0.3 mmol). The final product was triturated with ether to yield 157 mg (81%) of the desired material.
