Reaction Steps

To 0.05 g (0.1 mmol) of above resin-bound 3-(4-bromo-phenyl)-2-(S)-[(4′-trifluoromethyl-4-hydroxy-biphenyl-3-carbonyl)-amino]-propionic acid methyl ester in 2.0 mL of DME was added 50.1 mg (0.3 mmol) of 4-nitrophenylboronic acid, 30 mg (0.03 mmol) of Pd(PPh3)4, and 0.3 mL (0.6 mmol) of 2N Na2CO3 solution. The mixture was heated at 80° C. for 12 h. The resin was washed with H2O, DMF, MeOH, DCM three times of each and cleaved with TMSBr/TFA/DCM (1:1:5) at rt for 4 h. The residue obtained after removing the solvent was purified by chromatography (100% DCM) to give 28.2 mg of the title compound. LC/MS (m/z): 565 (M+1)+.
