4-Iodoaniline (6.9 g, 31.7 mmol), (2,4-dichlorophenyl)boronic acid (7.3 g, 38.0 mmol), Pd(dppf)Cl2 (1.3 g, 1.6 mmol), and 2M aqueous K2CO3 (31.7, 63.4 mmol) were dissolved in 1,4-dioxane (127 mL) and the resulting mixture was heated to 70° C. After 2.5 d the resulting mixture was cooled to room temperature, concentrated, diluted with EtOAc and 4M aqueous NaCl, and the layers were separated. The aqueous layer was extracted with EtOAc and the combined organics were dried (Na2SO4), concentrated, and purified via column chromatography to yield the title compound.
