反応手順

Using analogous reagents and reaction conditions as described in Example 1 above, 1-(4-cyclopropylpyridin-3-yl)imidazolidin-2-one (I-1d: 70 mg, 0.344 mmol) was reacted with 2-bromonaphthalene (85.68 mg, 0.413 mmol), 1,4-dioxane (5 mL), copper iodide (6.5 mg, 0.034 mmol), trans-N,N′-dimethylcyclohexane-1,2-diamine (4.8 mg, 0.034 mmol) and potassium phosphate (219 mg, 1.034 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% methanol in CHCl3), followed by preparative HPLC afforded 13 mg of the product (12% yield).
