Reaction Steps
To a degassed mixture of 4-benzyl-6-(4-bromo-phenyl)-morpholine (0.45 g; 1.35 mmol), sodium benzenesulfinate (0.27 g; 1.63 mmol), Cs2CO3 (0.66 g; 2.03 mmol), and tetrabutylammonium chloride (0.45 g; 1.63 mmol) in toluene (10 mL), was added Pd2dba3 (31.01 mg; 0.03 mmol) and Xantphos (39.19 mg; 0.07 mmol). The resulting mixture was heated under reflux for 2 days. After cooling to RT, EtOAc and a 5% aqueous NaHCO3 solution were added. The layers were separated and the organic layer was dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by column chromatography (SiO2, Et2O) to afford 2-(4-benzenesulfonyl-phenyl)-4-benzyl-morpholine (0.28 g).
