Vorschrift

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 321.4 mg, 1.8142 mmol) was reacted with 3-bromo-4-chloro-thieno[3,2-c]pyridine (500 mg, 1.9956 mmol), 1,4-dioxane (50 mL), copper iodide (34.4 mg, 0.1845 mmol), trans-1,2-diamino cyclohexane (62.3 mg, 0.5434 mmol) and potassium phosphate (961.3 mg, 4.528 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 220 mg of 1-(4-Chloro-thieno[3,2-c]pyridin-3-yl)-3-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (35.2% yield).
