Reaction Steps

A mixture of 5-bromo-N-(2-bromophenyl)nicotinamide 6 (3.44 g, 9.7 mmol), CuI (0.106 g, 0.56 mmol), Cs2CO3 (3.91 g, 12 mmol) and 1,10-phenanthroline (0.20 g, 1.12 mmol) in anhydrous 1,4-dioxane (50 ml) was heated at 100° C. overnight. After cooling to RT, the mixture was poured into ethyl acetate (200 ml), then washed with water. The aqueous phase was extracted with ethyl acetate (200 ml×2), and the organic phase was collected and dried over Na2SO4, purified by flash chromatography (silica gel, hexanes/ethyl acetate 3:1) to give a light yellow solid 7 (2.0 g, 75% yield).
