Procedure
In analogy to the procedure described for the synthesis of example 44 (step c), the title compound {(3S,4R)-4-(4-chloro-phenyl)-1-[1-(6-chloro-pyridazin-3-yl)-piperidine-4-carbonyl]-pyrrolidin-3-yl}-methyl-carbamic acid 4-fluoro-phenyl ester was prepared from [(3S,4R)-4-(4-chloro-phenyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-fluoro-phenyl ester using 1-(6-chloro-3-pyridazinyl)-4-piperidinecarboxylic acid instead of 1-methylcyclopropane-1-carboxylic acid and was obtained as an off-white foam.
