実験手順

To a stirred solution of carbonic acid ditrichloromethyl ester (triphosgene) (37 mg, 0.125 mmol) in CH2Cl2 (10 ml) at −78° C., was added a solution of [(3RS,4SR)-4-(3,4-Dichloro-phenyl)-pyrrolidin-3-yl]-(3-fluoro-4-trifluoromethyl-benzyl)-methyl-amine (Intermediate VIII-1), (130 mg, 0.31 mmol) and pyridine (0.05 ml, 0.68 mmol) in CH2Cl2 (5 ml) over 30 minutes. The temperature was raised to RT, and stirring was continued for 2 hours. The organic phase was washed with H2O, dried over Na2SO4. Purification by flash chromatography (SiO2, EtOAc/Hx 1:2) yielded 83 mg (55%) of the title compound as a light yellow oil.
