Reaction Steps

In analogy to the procedure described for the synthesis of example 87 (step c), the title compound N-{(3RS,4SR)-4-(3,4-dichloro-phenyl)-1-[2-(1,1-dioxo-1lambda*6*-thiomorpholin-4-yl)-acetyl]-pyrrolidin-3-yl}-2-(4-fluoro-phenyl)-N-methyl-acetamide was prepared from N-[(3RS,4SR)-4-(3,4-dichloro-phenyl)-pyrrolidin-3-yl]-2-(4-fluoro-phenyl)-N-methyl-acetamide using (1,1-Dioxo-1lambda*6*-thiomorpholin-4-yl)-acetic acid instead of 1-(1-methyl-cyclopropanecarbonyl)-piperidine-4-carboxylic acid and was obtained as a colorless oil. MS m/e: 556.1 [M]+.
