Reaction Steps

A mixture of 2-[(2,4-difluorobenzyl)oxy]-5-trifluoromethylbenzene boronic acid (66 mg, 0.2 mmol), methyl 4-(acetylamino)-2′-bromo-2-biphenylcarboxylate (110 mg, 0.32 mmol), potassium carbonate (138 mg, 1 mmol) and tetrakis(triphenylphosphine)palladium(0) (23 mg, 5 mol %) in 1:1 toluene/ethanol (4 ml) was stirred and heated at 90° C. under nitrogen for 2 hours. After cooling the mixture was diluted with diethyl ether and water and the organic phase dried (MgSO4) and evaporated to dryness. The residue was chromatographed with ethyl acetate/iso-hexane (2:3) to yield the title compound as a pale yellow gum. (90 mg).
