Reaction Steps

In analogy to the procedure described for the synthesis of example 73, the title compound rac-{(3R,4S)-4-(3,4-dichloro-phenyl)-1-[1-(tetrahydro-pyran-4-carbonyl)-piperidine-4-carbonyl]-pyrrolidin-3-yl}-methyl-carbamic acid 4-fluoro-phenyl ester was prepared from rac-[(3R,4S)-4-(3,4-dichloro-phenyl)-1-(piperidine-4-carbonyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-fluoro-phenyl ester using tetrahydro-2H-pyran-4-carbonyl chloride instead of propionyl chloride and was obtained as a white foam. MS m/e: 606.3 [M]+.
