실험 절차

To a stirred solution of [(3RS,4SR)-1-benzyl-4-(4-chloro-3-fluoro-phenyl)-pyrrolidin-3-yl]-methyl-amine (340 mg, 1.06 mmol) in MeOH (6 ml) was added 3-fluoro-4-trifluoromethyl-benzaldehyde (230 mg, 1.20 mmol). Then a solution of NaBH3CN (85 mg, 1.3 mol) in MeOH (1.5 ml) and AcOH (0.01 ml) were added. The reaction mixture was stirred overnight at RT, concentrated under vacuo, diluted with EtOAc, washed with H2O. The organic phases were dried over Na2SO4 and the product purified by flash chromatography (SiO2, EtOAc/Heptane 1:4) to afford 145 mg (28%) of the title compound as a colorless oil.
