반응 단계

Using the same reaction conditions as in Example 14, 1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 150 mg, 0.684 mmol) was reacted with 3-bromo-4-trifluoromethyl-pyridine (185.75 mg, 0.822 mmol), 1,4-dioxane (10 mL), copper iodide (12.99 mg, 0.0684 mmol), trans-1,2-diamino cyclohexane (23.37 mg, 0.205 mmol) and potassium phosphate (435 mg, 2.052 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in CHCl3), followed by preparative HPLC afforded 7 mg of the product (12.04% yield).
