実験手順

The resin-bound 3-(biphenyl-4-yl)-(2S)-(5-bromo-4-hydroxy-benzoylamino)-propionic acid methyl ester (50 mg, 0.3 mmol) was reacted with 3-chloro-4-fluorophenylboronic acid (240 mg, 1.5 mmol) following general procedure D, cleaved with TMSBr/TFA/DCM (1:1:5) at rt for 4 h. The residue obtained after removing the solvent was purified by chromatography to give 35 mg of title compound.
