Procedure

A mixture of methyl 2-(5-bromo-2-chlorophenyl)hydrazine carboxylate (i.e. the product of Step B) (1.27 g, 4.5 mmol), [3-(trifluoromethoxy)phenyl]boronic acid (1.85 g, 9 mmol), cesium carbonate (2.9 g, 9 mmol), tris(dibenzylideneacetone)dipalladium (0.18 g, 0.2 mmol) and triphenylphosphine (1.2 g, 4.5 mmol) in toluene (60 mL) and methanol (60 mL) was heated at refluxed for 24 h. After cooling, the reaction mixture was taken up in diethyl ether and washed with water. After drying over sodium sulfate, the solvent was removed under reduced pressure. The residue was purified by flash chromatography using 25% ethyl acetate in hexanes as eluant to afford a solid matieral (1.3 g), which was a mixture of starting material and the title compound.
