Procedure

To a solution of 459 mg of 4-[4-(4-cyanophenyl)-2,5-dioxo-4-[(2-propenyloxy)methyl]imidazolidin-1-yl]-2-trifluoromethylbenzonitrile obtained in Step 4 in DMF (1.5 mL), 173 mg of potassium carbonate and 130 μL of methyliodide are added. The mixture is stirred 3 hours at rt, evaporated, washed with brine, extracted with ethyl acetate, dried over magnesium sulfate and concentrated to give the desired compound.
