Reaktionsschritte

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 160 mg, 0.9039 mmol) was reacted with 4-bromo-1-fluoro-2-methyl-benzene (0.135 mL, 0.7142 mmol), 1,4-dioxane (15 mL), copper iodide (0.005 g, 0.0263 mmol), trans-1,2-diamino cyclohexane (0.015 g, 0.1315 mmol) and potassium phosphate (0.575 g, 2.7094 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform) afforded 26 mg of the product (30% yield).
