Reaction Steps

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 600 mg, 3.3898 mmol) was reacted with 2-chloro-4-iodo-pyridine (974 mg, 4.067 mmol), 1,4-dioxane (60 mL), copper iodide (65 mg, 0.3398 mmol), trans-1,2-diamino cyclohexane (0.12 mL, 1.0169 mmol) and potassium phosphate (2.15 g, 10.1694 mmol) to afford 810 mg of the product (83% yield).
