4-Bromoaniline (4.0 g, 23.3 mmol), (4-(tert-butyl)phenyl)boronic acid (4.6 g, 25.6 mmol), Pd(dppf)Cl2 (1.9 g, 2.3 mmol), and K2CO3 (6.4 g, 46.5 mmol) were dissolved in 1,4-dioxane (100 mL) and water (25 mL) and the resulting mixture was heated to 80° C. After 3 h the resulting mixture was cooled to room temperature, diluted with EtOAc, washed with water and brine, dried (Na2SO4), and dry packed onto silica gel. Column chromatography yielded the title compound.
