Using the same reaction conditions as described in example 14, 1-benzothiazol-6-yl-imidazolidin-2-one (I-84b: 600 mg, 2.739 mmol) was reacted with 3-bromo-4-ethyl-pyridine (512 mg, 2.739 mmol), 1,4-dioxane (10 mL), copper iodide (52 mg, 0.2739 mmol), trans-1,2-diamino cyclohexane (94.08 mg, 0.82 mmol) and potassium phosphate (1.74 mg, 8.2 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3), followed by preparative HPLC afforded 30 mg of the product (3.75% yield).
