S-phenyl-S-bicyclo[1.1.1]pentylsulfoximine (50 mg, 241 µmol, 1.00 equiv.), Cu2O (6.9 mg, 48.2 µmol, 20 mol%) and KOtBu (54 mg, 482 µmol, 2.00 equiv.) were mixed in a dry vial under argon atmosphere. Then, dimethylformamide (DMF) (0.5 mL), 1-iodo-2-methylbenzene (46 µL, 79 mg, 362 µmol, 1.50 equiv.) and 1,2-dimethylethylenediamine (DMEDA) (5.2 µL, 4.2 mg, 48.2 µmol, 20 mol%) were added. The mixture was stirred at 100 °C for 18 h. After cooling to 21 °C, the mixture was diluted with CH2Cl2, filtered through a short silica pad and the solvent was removed under reduced pressure.
