Reaction Steps

A mixture of methyl 2,5-diiodobenzoate prepared above (1.04 g, 2.67 mmol), 2-hydroxypyridine 1-7 (0.254 g, 2.67 mmol), 8-hydroxyquinoline (0.077 g, 0.53 mmol) and K3PO4 (1.13 g, 5.33 mmol) in dioxane (8 mL) was degassed with Ar before being charged with CuI (0.101 g, 0.53 mmol). The mixture in a sealed tube was heated at 130° C. overnight. It was then purified by HPLC to give 2-iodo-5-(2-oxopyridin-1(2H)-yl)benzoic acid (0.220 g). MS 342.0 (M+H).
