Reaction Steps

CuI (10 mg, 0.05 mmol), N,N-diethylsalicylamide (10 mg, 0.05 mmol), 4-toluidine (161, 1.5 mmol) and K3PO4 (425 mg, 2.0 mmol) were put into a screw-capped test tube with a Teflon-lined septum. The tube was then evacuated and backfilled with argon (3 cycles). 5-Bromo-m-xylene (136 μL, 1.0 mmol) was added by a syringe. The reaction mixture was stirred at 100° C. for 20 h. The reaction mixture was allowed to reach room temperature. Ethyl acetate (˜2 mL), water (˜10 mL), ammonium hydroxide (˜0.5 mL) and dodecane (227 μL) were added. The organic phase was analyzed by GC and 22% conversion of 5-bromo-m-xylene and 9% GC yield of the desired product was obtained.
