Reaction Steps

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 150 mg, 0.8474 mmol) was reacted with 1-bromo-4-chloro-benzene (162 mg, 0.8474 mmol), 1,4-dioxane (5 mL), copper iodide (16.142 mg, 0.08474 mmol), trans-1,2-diamino cyclohexane (29.108 mg, 0.2542 mmol) and potassium carbonate (234.3 mg, 1.6948 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform) afforded 155 mg of the product (63.78% yield).
