反応手順

Using the same reaction conditions as in Example 14, 1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 75 mg, 0.3173 mmol) was reacted with 3-bromo-4-difluoromethyl-pyridine (60 mg, 0.2884 mmol), 1,4-dioxane (5 mL), copper iodide (7.5 mg), trans-1,2-diamino cyclohexane (15 mg) and potassium phosphate (122 mg, 0.5769 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3), followed by preparative HPLC afforded 2 mg of the product (2% yield).
