実験手順
In analogy to the procedure described for the synthesis of [(3S,4R)-1-Benzyl-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-fluoro-phenyl ester (example 265, a) the title compound was prepared from rac-[(3S,4R)-1-Benzyl-4-(4-fluoro-phenyl)-pyrrolidin-3-yl]-methyl-amine (WO2008128891) and 4-fluorophenyl chloroformate. MS m/e: 423.3 [M+H]+. This was followed by column chromatography on Chiralpak AD eluting with a gradient formed from ethanol and heptane. The product containing fractions were evaporated to yield the title compound as off-white solid. MS m/e: 423.3 [M+H]+.
