An oven-dried test tube was purged with argon and charged with Pd2(dba)3 (4.6 mg, 0.005 mmol, 1.0 mol % Pd), 2 [Example 1] (6.0 mg, 0.015 mmol, 1.5 mol %), and NaOt-Bu (135 mg, 1.40 mmol). The test tube was fitted with a septum, then toluene (2.0 mL), N-methylaniline (135 μL, 1.25 mmol), and 2-chloro-p-xylene (135 μL, 1.01 mmol) were added. The mixture was stirred at 80° C. for 13 h, then cooled to room temperature, diluted with ether (20 mL), filtered and concentrated. The crude material was purified by flash chromatography on silica gel to afford 202 mg (95%) of a colorless oil.
