Procedure

Using the same reaction conditions as described in example 14, 4,4-dimethyl-1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-163b: 150 mg, 0.731 mmol) was reacted with 6-iodo-benzothiazole (248 mg, 0.950 mmol), 1,4-dioxane (10 mL), copper iodide (13 mg, 0.0682 mmol), trans-1,2-diamino cyclohexane (31 mg, 0.218 mmol) and potassium phosphate (387 mg, 1.825 mmol) to afford the crude product. Purification by column chromatography on silica gel (1% MeOH in CHCl3) afforded 30 mg of the product (12.14% yield).
