Vorschrift

Using the same reaction conditions as in Example 1, 1-pyridin-3-yl-imidazolidin-2-one (I-1b: 95 mg, 0.5882 mmol) was reacted with 6-bromo-1-ethyl-3,4-dihydro-1H-quinolin-2-one (150 mg, 0.5882 mmol), 1,4-dioxane (5 mL), copper iodide (11 mg, 0.05882 mmol), trans-1,2-diamino cyclohexane (10 mg, 0.08823 mmol) and potassium carbonate (162 mg, 1.1764 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in chloroform), afforded 94 mg of the product (47.71% yield).
