実験手順

Using the same reaction conditions as in Example 14, 1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 250 mg, 1.4108 mmol) was reacted with 3-iodo-imidazo[1,2-a]pyridine (344 mg, 1.4108 mmol), 1,4-dioxane (10 mL), copper iodide (34 mg), trans-1,2-diamino cyclohexane (68 mg) and potassium phosphate (898 mg, 4.2325 mmol) to afford the crude product. Purification by column chromatography on silica gel (10% MeOH in CHCl3) afforded 82 mg of the product (19.81% yield).
