Using the same reaction conditions and work up as described in Example 1, step-3,1-benzothiazol-6-yl-5-trifluoromethyl-imidazolidin-2-one (I-172b: 0.15 g, 0.0005 mol) was refluxed with 3-Iodo-4-methyl-pyridine (0.168 g, 0.0007 mol), copper iodide (0.01 g, 0.00005 mol), N,N′-Dimethyl-cyclohexane-1,2-diamine (0.01 g, 0.000015 mol), potassium phosphate (0.3 g, 0.001 mol) and 1,4-dioxane (20 mL) at 120° C. for 12 hours to afford the crude product. The reaction was monitored by TLC (100% ethyl acetate). Purification by column chromatography on silica gel (2% methanol in DCM) afforded 75 mg of the product (39.47% yield).
