実験手順
To a stirred solution of [(3RS,4SR)-1-benzyl-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-methyl-(4-trifluoromethyl-benzyl)-amine (160 mg, 0.32 mmol) in CH3CN (5 ml) at RT, was added 2,2,2-trichloroethyl chloroformate (0.070 ml, 0.48 mmol). The reaction mixture was stirred at RT for 3 hours, concentrated under vacuo. The residue was dissolved in AcOH (3 ml) and zinc dust (80 mg) was added portion wise over 1 hours. The solvent was evaporated, the residue diluted in EtOAc and the organic phase was washed with an aqueous solution of NaHCO3. The organic phase was dried over Na2SO4 and concentrated under vacuo. The product was purified by column chromatography (CH2Cl2/MeOH: 9/1) to afford 85 mg (65%) of the tile compound as a colorless oil. ES-MS m/e: 403.4 (M+H+).
