반응 단계
A test tube was charged with CuI (10 mg, 0.05 mmol, 0.05 equiv), K3PO4 (425 mg, 2.0 mmol, 2.0 equiv), butylurea (232 mg, 2.0 mmol, 2.0 equiv), filled with argon. 3-Iodoanisole (119 μL, 1.0 mmol, 1.0 equiv), N,N′-dimethylethylendiamine (11 μL, 0.10 mmol, 0.10 equiv) and dry toluene (1.0 mL) were added under argon. The test tube was sealed and the reaction mixture was stirred at 110° C. for 24 h. The resulting suspension was cooled to room temperature and filtered through a 0.5×1 cm pad of silica gel, eluting with diethyl ether. The filtrate was concentrated in vacuo. Purification of the residue by flash chromatography on silica gel (2×20 cm; pentane:diethyl ether 1:2) provided 188 mg (85% yield) of the title compound as a light yellow oil.
