Versuchsvorschrift
3-(4-Chloro-3-trifluoromethyl-phenyl)-5-hydroxymethyl-5-methyl-imidazolidine-2,4-dione from Example 10 (1.01 g, 3.14 mmoL) in DCM (10 mL) was treated with TEA (0.66 mL, 4.70 mmoL) followed by MsCl (360 mg, 3.14 mmoL) at 0° C., The reaction was slowly warmed to room temperature and stirring for another 2 hrs. The crude product was partitioned between DCM and water. The organic layer was washed with sat. NaHCO3, brine, dried over anhydrous Na2SO4, filtered and concentrated, then purified by silica gel column chromatography using heptane and ethyl acetate as eluent to afford the title compound as a white solid (1.05 g, yield 85%).
