Procedure

To a stirred solution of [(3RS,4SR)-1-benzyl-4-(3-chloro-phenyl)-pyrrolidin-3-yl]-methyl-amine (2.20 g, 7.31 mmol) in THF (70 ml) was added 4-bromomethyl-2-fluoro-1-trifluoromethyl-benzene (2.25 g, 8.75 mmol) and Et3N (1.21 ml, 8.75 mmol). The reaction mixture was stirred overnight at 40° C., concentrated under vacuo, diluted with EtOAc, washed with H2O. The organic phase was dried over Na2SO4 and the product purified by flash chromatography (SiO2, EtOAc/Heptane 1:3) to afford 2.0 g (57%) of the title compound as a colorless oil.
