실험 절차
In analogy to the procedure described in example 192 h, (2S,4R)-4-benzenesulfonyl-1-(3-oxo-thiobutyryl)-pyrrolidine-2-carboxylic acid methyl ester (example 261d) was reacted with (2-chloro-pyridin-4-yl)-hydrazine (CAS Reg. No. 700811-29-6) to give the title compound as yellow solid. MS (ESI): m/z=461.3 [M+H]+.
