1-[3-(4-Iodophenoxy)propyl]-pyrrolidine (66 mg, 0.2 mmol), indole (28 mg, 0.24 mmol), copper(I) iodide (0.4 mg, 0.002 mmol), trans-1,2-diaminocyclohexane (0.0024 mmol, 0.02 mmol), and potassium phosphate tribasic (89 mg, 0.42 mmol) were stirred at 90° C. in dioxane overnight. The reaction mixture was filtered through celite and washed with dichloromethane. The filtrate was concentrated, and the resulting residue was purified by semi-prep LC-MS to give 22.4 mg of the desired product (35% yield).
