Reaction Steps

In analogy to the procedure described for the synthesis of example 140, the title compound N-[(3RS,4SR)-1-(1-Cyclopropanesulfonyl-piperidine-4-carbonyl)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-4-methoxy-N-methyl-3-trifluoromethyl-benzamide was prepared from N-[(3RS,4SR)-4-(3,4-dichloro-phenyl)-1-(piperidine-4-carbonyl)-pyrrolidin-3-yl]-4-methoxy-N-methyl-3-trifluoromethyl-benzamide using cyclopropanesulfonylchloride instead of ethanesulfonyl chloride and was obtained as a off-white foam. MS m/e: 662.2 [M]+.
