3-(Biphenyl-4-yl)-(2S)-[(3'-chloro-4'-fluoro-4-hydroxy-biphenyl-3-carbonyl)-amino]-propionic Acid Methyl Ester → 2-(S)-(3-Hydroxy-naphthalene-2-carbonyl)-amino-3-(4-bromophenyl)-propionic acid methyl ester

Participants

Reaction Steps

1.0 g (2.5 mmol) of resin-bound naphthoic acid obtained in Example 1 was reacted with 1.95 g (7.5 mmol) of (2S)-Amino-3-(4-bromophenyl)-propionic acid methyl ester as described in the general procedure A to give resin-bound 2-(S)-(3-Hydroxy-naphthalene-2-carbonyl)-amino-3-(4-bromophenyl)-propionic acid methyl ester.
