실험 절차

In analogy to the procedure described in example 253e, (2S,4R)-4-benzenesulfonyl-1-[2-(2-chloro-pyridin-4-yl)-5-methyl-2H-pyrazol-3-yl]-pyrrolidine-2-carboxylic acid methyl ester was saponified in the presence of lithium hydroxide to give the title compound as yellow solid. MS (ESI): m/z=447.2 [M+H]+.
