Reaction Steps

A mixture of 4-chloro-1-iodo-2-methoxy-benzene (0.268 g, 1 mmol), imidazole (0.082 g, 1.2 mmol), 1,0-phenanthroline (0.018 g, 0.1 mmol), CuI (0.01 g, 0.05 mmol), and Cs2CO3 (0.684 g, 2.1 mmol) in dioxane (1.5 mL) was heated at 110° C. for 24 hours. After the reaction mixture cooled to room temperature, it was partitioned between H2O and EtOAc. The aqueous layer was extracted with additional EtOAc. The combined organic layers were washed with water, brine, dried over MgSO4 and concentrated under reduced pressure. The residue was purified by silica gel column chromatography, eluting with EtOAc to give 0.095 g of the title compound (46%). MS (APCI) m/e 209 (M+H)+, 1H NMR (500 MHz, DMSO-d6): □ 7.44 (s, 1H), 7.43 (s, 1H), 7.35 (d, J=2.14 Hz, 2H), 7.15 (d, J=2.14 Hz, 1H), 7.13 (d, J=2.14 Hz, 1H), 3.86 (s, 3H).
