Procedure

To a stirred solution of [(3RS,4SR)-1-benzyl-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-methyl-amine (0.35 g, 1.04 mmol) in THF (6 ml) was added 1-bromomethyl-4-trifluoromethyl-benzene (0.27 g, 1.15 mmol) and Et3N (0.148 ml, 1.45 mmol). The reaction mixture was stirred overnight at RT and concentrated under vacuo. The product purified by flash chromatography (SiO2, EtOAc/Heptane 1:4) to afford 130 mg (29%) of the title compound as a colorless oil. ES-MS m/e: 492.9 (M+H+).
