Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 100 mg, 0.5649 mmol) was reacted with 4-bromo-2-methyl-pyridine (97 mg, 0.5649 mmol), 1,4-dioxane (5 mL), copper iodide (10.76 mg, 0.05649 mmol), trans-1,2-diamino cyclohexane (19.4 mg, 0.1694 mmol) and potassium phosphate (359.58 mg, 1.694 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 132 mg of the product (88.0% yield).
