Reaction Steps

Using the same reaction conditions as in Example 15, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 150 mg, 0.847 mmol) was reacted with 4-bromo-2-trifluoromethyl-pyridine (229 mg, 1.017 mmol), 1,4-dioxane (10 mL), copper iodide (16.13 mg, 0.0847 mmol), trans-1,2-diamino cyclohexane (29.09 mg, 0.254 mmol) and potassium phosphate (44.89 mg, 2.117 mmol). The resulting mixture was heated to 120° C. for 6 hours. The reaction workup afforded 200 mg of the product (73.52% yield).
