Reaction Steps

Using analogous reagents and reaction conditions as described in Example 1 above, 1-(4-cyclopropylpyridin-3-yl)imidazolidin-2-one (I-1d: 90 g, 0.443 mmol) was reacted with 5-bromo-6-fluorobenzo[b]thiophene (I-28d: 102 mg, 0.443 mmol), 1,4-dioxane (4 mL), copper iodide (9 mg, 0.044 mmol), trans-N,N′-dimethylcyclohexane-1,2-diamine (19 mg, 0.132 mmol) and potassium phosphate (282 mg, 1.329 mmol) to afford the crude product. Purification by preparative HPLC afforded 9 mg of the product (6% yield).
