Reaction Conditions

Reaction Steps

A microwave test tube was charged with CuI (20 mg, 0.10 mmol, 0.10 equiv), K3PO4 (425 mg, 2.0 mmol, 2.0 equiv), 2-imidazolidone (1.29 g, 15.0 mmol, 15.0 equiv), 3-iodoanisole (119 μL, 1.0 mmol, 1.0 equiv), N,N′-dimethylethylenediamine (22 μL, 0.20 mmol, 0.20 equiv) and dry DMF (2.0 mL), filled with argon. The test tube was sealed and the reaction mixture was stirred at 130° C. for 15 h in the microwave. The resulting suspension was cooled to room temperature and filtered through a 0.5×1 cm pad of silica gel, eluting with ethyl acetate. The filtrate was concentrated in vacuo. Purification of the residue by flash chromatography on silica gel (2×20 cm; hexane:ethyl acetate 1:2) provided 128 mg (67% yield) of the title compound as a white solid.
