Using the same reaction conditions as in Example 1, 1-pyridin-3-yl-imidazolidin-2-one (I-1b: 95.8 mg, 0.5882 mmol) was reacted with 6-bromo-2-chloro-4-methyl-quinoline (150 mg, 0.5882 mmol), 1,4-dioxane (5 mL), copper iodide (11.2 mg, 0.05882 mmol), trans-1,2-diamino cyclohexane (20.20 mg, 0.1764 mmol) and potassium carbonate (162.6 mg, 1.1764 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform) afforded 70 mg of the product (35.17% yield).
