Procedure

In analogy to the procedure described for the synthesis of example 44 (step c), the title compound {(3S,4R)-4-(3,4-dichloro-phenyl)-1-[1-(6-methyl-pyridazin-3-yl)-piperidine-4-carbonyl]-pyrrolidin-3-yl}-methyl-carbamic acid 4-trifluoromethyl-cyclohexyl ester was prepared from [(3S,4R)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-trifluoromethyl-cyclohexyl ester instead of [(3S,4R)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-methyl-carbamic acid 4-fluoro-phenyl ester using 1-(6-methyl-pyridazin-3-yl)-piperidine-4-carboxylic acid instead of 1-methylcyclopropane-1-carboxylic acid and was obtained as an off-white foam. MS m/e: 642.4 [M]+.
