Procedure

1-(4-Bromophenyl)-5-methoxy-2-methyl-1H-indole and 1-(4-Iodophenyl)-5-methoxy-2-methyl-1H-indole. 5-Methoxy-2-methylindole (500 mg, 3.1 mmol) and 1-bromo-4-iodobenzene (877 mg, 3.1 mmol) were dissolved in toluene (6 mL). To the resulting solution were added copper(I) iodide (12 mg, 0.062 mmol), potassium phosphate tribasic (1.32 g, 6.2 mmol), and N,N′-dimethylethylenediamine (6.6 μL, 0.062 mmol). The mixture was heated at 80° C. overnight, allowed to cool to room temperature and filtered through a pad of silica. The resulting solution was concentrated to give a mixture of both the bromo and the iodo halophenyl indoles, which were used without further purification (assumed quantitative).
