Reaction Steps

1-{4′-[4-(6-Bromo-pyridin-2-ylamino)-3-methyl-isoxazol-5-yl]-biphenyl-4-yl}-cyclopropanecarboxylic acid ethyl ester (0.200 g, 0.386 mmol) was dissolved in toluene along with phenylacetylene (0.051 mL, 0.46 mmol), copper(I) iodide (0.367 g, 1.93 mmol), triethylamine (0.269 mL, 1.93 mmol) and bis(triphenylphosphine)palladium(II) dichloride (0.032 g, 0.039 mmol). The reaction was heated to 40° C. for 3 days then cooled, diluted with EtOAc and filtered through a plug of silica gel. The crude material was purified on silica gel to yield the title compound.
