Reaction Steps

To 5-bromo-N-(2-cyclohexyl-1,5-dimethyl-3-oxo-2,3-dihydro-1H-pyrazol-4-yl)-4-methylisoxazole-3-carboxamide (75 mg, 0.189 mmol) was added cyclohexylzinc(II) bromide (0.5M in THF) (1133 μL, 0.566 mmol) and bis(tri-t-butylphosphine)palladium(0) (9.65 mg, 0.019 mmol) and the mixture was stirred at 100° C. in the microwave for 30 minutes. The resulting mixture was diluted with EtOAc and filtered and the solvent was removed under reduced pressure. The crude material was adsorbed onto silica and purification by chromatography eluting with 0-100% EtOAc in iso-hexane afforded the title compound;
