Reaction Steps

In analogy to the procedure described for the synthesis of example 97, the title compound 3-bromo-4-chloro-N-{(3RS,4SR)-4-(3,4-dichloro-phenyl)-1-[1-(1-methyl-cyclopropanecarbonyl)-piperidine-4-carbonyl]-pyrrolidin-3-yl}-N-methyl-benzamide was prepared from {4-[(3SR,4RS)-3-(3,4-dichloro-phenyl)-4-methylamino-pyrrolidine-1-carbonyl]-piperidin-1-yl}-(1-methyl-cyclopropyl)-methanone using 3-bromo-4-chlorobenzoic acid instead of 4-chloro-3-(trifluoromethyl)benzoic acid and was obtained as a colorless oil. MS m/e: 656.0 [M]+.
