Vorschrift

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 79.79 mg, 0.4508 mmol) was reacted with 2-bromo-5-fluoro-3-methyl-benzo[b]thiophene (110 mg, 0.4508 mmol), 1,4-dioxane (5 mL), copper iodide (8.58 mg, 0.04508 mmol), trans-1,2-diamino cyclohexane (15.48 mg, 0.1352 mmol) and potassium carbonate (124.6 mg, 0.9016 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform) afforded 84 mg of the product (60.45% yield).
