Reaction Steps

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 150 mg, 0.847 mmol) was reacted with 2-bromo-thiophene (0.08 mL, 0.847 mmol), 1,4-dioxane (10 mL), copper iodide (16.13 mg, 0.0847 mmol), trans-1,2-diamino cyclohexane (0.03 mL) and potassium carbonate (233 mg, 1.694 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in DCM) afforded 240 mg of the product (48.4% yield).
