4-Bromo-L-phenylalanine → (1S,5S) [1-{5-[(4-amino-benzenesulfonyl)-isobutyl-amino]-6-phosphonooxy-hexylcarbamoyl}-2-(4-bromo-phenyl)-ethyl]-carbamic acid methyl ester

Participants

Reaction Steps

This derivative was synthesized using the procedure described for the preparation of (1S,5S)-[1-{5-[(4-amino-benzenesulfonyl)-isobutyl-amino]-6-phosphonooxy-hexylcarbamoyl}-2-(2-bromo-phenyl)-ethyl]-carbamic acid methyl ester (example 4, steps A and B) using L-4-bromophenylalanine (Peptech Corp.) instead of L-2-bromophenylalanine. The desired material was obtained in 28% yield (25 mg)
