Procedure

The resin-bound 3-(4-bromo-phenyl)-(2S)-[(4′-trifluoromethyl-4-hydroxy-biphenyl-3-carbonyl)-amino]-propionic acid methyl ester (50 mg, 0.1 mmol) prepared as generally described in Example 37 was reacted with 4-nitro-phenyl boronic acid (50.1 mg, 0.3 mmol) by adapting the procedure as described in Example 43 to give title compound (28.2 mg, 50%). LC/MS (m/z): 565 (M+1)+.
