Reaction Steps

Using the same reaction conditions as in Example 15, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 295 mg, 1.65 mmol) was reacted with 4-bromo-2-fluoro-benzoic acid methyl ester (350 mg, 1.5 mmol), 1,4-dioxane (25 mL), copper iodide (32 mg, 0.165 mmol), trans-1,2-diamino cyclohexane (70 mg, 0.495 mmol) and potassium phosphate (875 mg, 4.12 mmol). The resulting mixture was refluxed for 18 hours. The reaction workup afforded 350 mg of 2-fluoro-4-[3-(4-methyl-pyridin-3-yl)-2-oxo-imidazolidin-1-yl]-benzoic acid methyl ester (68.7% yield).
