Using the same reaction conditions as in Example 14, 1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 0.150 g, 0.684 mmol) was reacted with 3-bromo-4-chloro-pyridine (0.157 g, 0.820 mmol), 1,4-dioxane (20 mL), copper iodide (0.012 g, 0.0684 mmol), trans-1,2-diamino cyclohexane (0.022 g. 0.20 mmol) and potassium phosphate (0.362 g, 1.71 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 85 mg of the product (37.7% yield).
