Participants

Reaction Steps

Heat 1-benzyl-2-methyl bromo-5-(2,4-difluorophenyl)-1H-imidazole (0.321 g, 0.885 mmol), N-[cyano]N-[isobutyl]2-nitro-5-(5,5-dimethyl-[1,3,2]dioxaborinan-2-yl)aniline (0.352 g, 1.06 mmol), palladium(II)acetate (0.0099 g, 0.044 mmol), di-tert-butylphosphinoferrocene (0.058 g, 0.177 mmol), and potassium carbonate (0.45 g, 3.26 mmol) in dioxane (10 mL) to 100° C. for 20 hours. Cool to room temperature and concentrate under reduced pressure. Subject residue to silica gel chromatography, eluting with dichloromethane/ethyl acetate mixtures to provide 0.191 g (0.38 mmol) of the title compound.
