2-(3-bromophenyl)-1-(2,6-diisopropylphenyl)-1H-imidazole (2.8 g, 7.30 mmol), Pd2(dba)3 (0.067 g, 0.073 mmol), dicyclohexyl(2′,6′-dimethoxy-[1,1′-biphenyl]-2-yl)phosphine (S-Phos) (0.120 g, 0.292 mmol), and sodium t-butoxide (1.053 g, 10.96 mmol) were mixed in 100 mL of xylene. The solution was bubbled with nitrogen for 20 min. N-phenyl-3-(pyridin-2-yl)aniline (1.979 g, 8.03 mmol) was added. The reaction was heated up to reflux for 6 h. After cooled to rt, dichloromethane was added. The mixture was filtered through Celite®. The solvent was then evaporated. The residue was coated on Celite® and columned with hexanes/ethyl acetate (3:1) to give 3-(1-(2,6-diisopropylphenyl)-1H-imidazol-2-yl)-N-phenyl-N-(3-(pyridin-2-yl)phenyl)aniline (3.66 g, 6.67 mmol, 91% yield).
