실험 절차

To 0.05 g (0.1 mmol) of above resin-bound 3-(biphenyl-4-yl)-(2S)-(5-bromo-4-hydroxy-benzoylamino)-propionic acid methyl ester in 2.0 mL of DME were added 52.0 mg (0.3 mmol) of 3-chloro-4-fluorophenylboronic 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 to 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 (DCM) to give 35 mg (70%) of title compound LC/MS (m/z): 490 (M+1)+.
