Procedure

To 120 mg (0.1 mmol) of above resin-bound bound N-(5-bromo-pyridin-2-yl)-2-[4-(3-hydroxy-4-nitro-phenoxy)-phenyl]-acetamide in 2.0 mL of DME were added 48.0 mg (0.3 mmol) of 3-chlorophenylboronic 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 (silica gel, DCM) to give 20 mg (40%) of the title compound.
