Reaction Steps

Using analogous reagents and reaction conditions as described in Example 1 above, 1-(3-trifluoromethyl-phenyl)-imidazolidin-2-one (I-36b: 200 mg, 0.869 mmol) was reacted with 3-bromo-isonicotinic acid ethyl ester (239 mg, 1.042 mmol), copper iodide (16.5 mg, 0.869 mmol), trans-N,N′-dimethylcyclohexane-1,2-diamine (37.01 mg, 0.26 mmol), potassium phosphate (460.5 mg, 2.172 mmol) and 1,4-dioxane (5 mL) to afford crude product. Purification by column chromatography on silica gel (60% ethyl acetate in hexane) afforded 280 mg of pure product (85% yield).
