Reaction Steps

An oven-dried resealable Schlenk tube was charged with CuI (10 mg, 0.0525 mmol, 5.0 mol %), 1,10-phenanthroline (20 mg, 0.111 mmol), sodium tert-butoxide (145 mg, 1.51 mmol), evacuated and backfilled with argon. Dodecane (235 μL), 5-iodo-m-xylene (150 μL, 1.04 mmol), N-methylaniline (135 μL, 1.25 mmol) and dioxane (1.0 mL) were added under argon. The Schlenk tube was sealed and the reaction mixture was stirred magnetically at 110° C. for 24 h. The resulting brown suspension was cooled to room temperature and filtered through a 0.5×1 cm pad of silica gel eluting with 10 mL of ethyl acetate. The filtrate was concentrated and the residue was purified by flash chromatography on silica gel (2×15 cm; hexane-ether 50:1; 10 mL fractions). Fractions 7-11 provided 110 mg (50% yield) of the product as a colorless oil. 1H NMR (400 MHz, CDCl3): δ 7.33−7.27 (m, 2H), 7.05−6.94 (m, 3H), 6.72 (s, 2H), 6.68 (s, 1H), 3.33 (s, 3H), 2.31 (s, 6H).
