A solution of 4-methoxy-3-trifluoromethyl-benzoyl chloride (commercially available) (0.88 g, 2.76 mmol) in CH2Cl2 (10 ml) was added drop wise to a stirred solution of rac-[(3S,4R)-1-benzyl-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-methyl-amine (0.80 g, 2.38 mmol) and ethyl-diisopropyl-amine (0.61 ml, 3.58 mmol) in CH2Cl2 (10 ml). The reaction mixture was stirred 4 h, concentrated under vacuo and purification by flash chromatography (SiO2, CH2Cl2/MeOH, 99:1) yielded 1.09 g (86%) of the title product as colorless oil. ES-MS m/e: 537.5 (M+H+).
