Participants

Reaction Steps

2-(S)-amino-3-biphenyl-4-yl-propionic acid methyl ester (128 mg, 0.5 mmol) was reacted with 3-bromo-5-chloro-2,6-dimethoxybenzoic acid (148 mg, 0.5 mmol) as described in general procedure A. The resulting crude compound was reacted with 195 mg (1.0 mmol) of 4-(trifluoromethyl)phenylboronic acid as described in general procedure D. The product thus obtained was hydrolyzed according to general procedure C to afford the title product (180 mg) as a pure white solid.
