Procedure

To a −78° C. stirring solution of 4-(4,4-Dimethyl-2-oxo-pyrrolidin-3-yloxy)-2-trifluoromethyl-benzonitrile (Compound (1), product of Example 3, Step E, 5.00 g, 16.8 mmoles) in 100 mL THF under a nitrogen atmosphere was added lithium bis(trimethylsilyl)amide (1 M in THF, 18.4 mL, 18.4 mmoles) and bromoacetic acid ethyl ester (2) (2.0 mL, 18.4 mmoles). The cooling bath was allowed to warm up to ambient temperature overnight. Water (25 mL) was added and the reaction mixture was concentrated in vacuo. Methylene chloride (100 mL) and water (50 mL) was added, the mixture is agitated and the layers are separated. The organic layer was concentrated in vacuo. The product (3) is used as is for the next reaction.
