Reaction Steps

Using the same reaction conditions as in Example 1, 1-pyridin-3-yl-imidazolidin-2-one (I-1b: 73 mg, 0.45 mmol) was reacted with 2-bromo-5-fluoro-3-methyl-benzo[b]thiophene (110 mg, 0.45 mmol), 1,4-dioxane (5 mL), copper iodide (8 mg, 0.045 mmol), trans-1,2-diamino cyclohexane (7 mg, 0.0675 mmol) and potassium carbonate (124 mg, 0.9 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform), afforded 90 mg of the product (61.64% yield).
