Reaction Steps

To a solution of 4-benzyl-2-(4-bromo-phenyl)-morpholine (2.00 g; 6.02 mmol) and 2,6-dimethylthiophenol (0.88 mL; 6.62 mmol) in DMF (15 mL) was added CuBr (0.43 g; 3.01 mmol), 1,2,3,4-tetrahydro-quinolin-8-ol (0.45 g; 3.01 mmol) and Cs2CO3 (2.45 g; 7.52 mmol; 1.25 eq.). The resulting mixture was heated, in a closed vessel, at 130° C., for 2 days. After cooling to RT, water was added and the mixture extracted with Et2O. The combined organic layers were washed with water, dried (Na2SO4), filtered and concentrated in vacuo. The residue was purified by column chromatography (Et2O/hexanes 1:1) to afford 4-benzyl-2-[4-(2,6-dimethyl-phenylsulfanyl)-phenyl]-morpholine (1.60 g).
