In analogy to the procedure described for the synthesis of example 87 (step c), the title compound N-[(3RS,4SR)-1-(1-cyclopropylmethyl-piperidine-4-carbonyl)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-2-(4-fluoro-phenyl)-N-methyl-propionamide was prepared from (1-cyclopropylmethyl-piperidin-4-yl)-[(3SR,4RS)-3-(3,4-dichloro-phenyl)-4-methylamino-pyrrolidin-1-yl]-methanone instead of N-[(3RS,4SR)-4-(4-chloro-phenyl)-pyrrolidin-3-yl]-4-methoxy-N-methyl-3-trifluoromethyl-benzamide using 4-fluoro-alpha-methylphenyl acetic acid instead of 1-(1-methyl-cyclopropanecarbonyl)-piperidine-4-carboxylic acid and was obtained as a colorless oil. MS m/e: 560.2 [M]+.
