Reaktionsschritte
Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 500 mg, 2.825 mmol) was reacted with 5-bromo-benzo[b]thiophene (661.86 mg, 3.12 mmol), 1,4-dioxane (20 mL), copper iodide (53.81 g, 0.2825 mmol), trans-1,2-diamino cyclohexane (97.03 g, 0.8475 mmol) and potassium phosphate (1.796 g, 8.475 mmol) to afford the crude product. Purification by column chromatography on silica gel (1.2% MeOH in CHCl3), followed by preparative HPLC afforded mg of the product (4.61% yield).
