実験手順
To a solution of 1,3-diiodobenzene (5.05 g, 15.3 mmol) in isopropanol (16 mL) under nitrogen was added morpholine (1.33 g, 1.33 mL, 15.3 mmol), potassium phosphate (6.50 g, 30.6 mmol), ethylene glycol (1.90 g, 1.70 mL, 30.6 mmol) and copper (I) iodide (146 mg, 0.765 mmol). The mixture was heated at 80° C. for 15 h, and then cooled to room temperature. The solids were removed by filtration and the solution was concentrated. The residue was purified by silica gel column chromatograghy eluted with EtOAc:hexanes (5 to 25% EtOAc) to give 4-(3-iodo-phenyl)-morpholine (1.81 g, 41%) as a colorless oil. MS (ES+): m/z=290.0; 1H NMR (CDCl3, 500 MHz): δ 3.15 (t, 4H), 3.85 (t, 4H), 6.87 (dd, 1H), 6.96-7.00 (m, 1H), 7.20 (d, 1H), 7.22-7.25 (m, 1H).
