Vorschrift

Using the same reaction conditions as in Example 1, 1-pyridin-3-yl-imidazolidin-2-one (I-1b: 62 mg, 0.3831 mmol) was reacted with 6-iodo-benzothiazole (100 mg, 0.3831 mmol), 1,4-dioxane (10 mL), copper iodide (7 mg, 0.03831 mmol), trans-1,2-diamino cyclohexane (6 mg, 0.5747 mmol) and potassium carbonate (105 mg, 0.7662 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform), afforded 52 mg of the product (46.01% yield).
