Versuchsvorschrift

To a solution of (3R,5R)-1-[4-(4-chlorophenoxy)phenyl]-5-[3-(trifluoromethyl)phenyl]-3-(2-hydroxyethyl)pyrrolidin-2-one (50 mg, 0.105 mmol) in DCM (2 mL) at 0° C. is added MsCl (26 μL) and TEA (50 μL). The reaction mixture is stirred at room temperature for 45 min before removal of the solvent. The residue is purified on silica gel (0-50% ethyl acetate in hexane) to give 2-{(3R,5R)-1-[4-(4-chlorophenoxy)phenyl]-5-[3-(trifluoromethyl)phenyl]-2-oxopyrrolidin-3-yl}ethyl methanesulfonate (54.3 mg, 93%) as a colorless oil.
