Procedure

1-(4-methyl-pyridin-3-yl)-imidazolidin-2-one (I-14b: 100 mg, 0.5643 mmol) was reacted with 2-bromo-5-trifluoromethyl-thiophene (136.9 mg, 0.5925 mmol), 1,4-dioxane (10 mL), copper iodide (10.75 mg, 0.0564 mmol), trans-1,2-diamino cyclohexane (20.4 mL, 0.1693 mmol) and potassium phosphate (360 mg, 1.693 mmol) to afford the crude product. Purification by column chromatography on silica gel (2% MeOH in CHCl3) afforded 120 mg of the product (65% yield).
