Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 0.500 g, 2.82 mmol) was reacted with 1-(5-bromo-2-fluoro-phenyl)-ethanone (0.612 g, 2.82 mmol), 1,4-dioxane (30 mL), copper iodide (53.81 mg, 0.282 mmol), trans-1,2-diamino cyclohexane (97.03 mg, 0.846 mmol) and potassium phosphate (1.79 g, 8.46 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 220 mg of 1-(3-Acetyl-4-fluoro-phenyl)-3-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (24.9% yield).
