In analogy to the procedure described in example 192 h, (2S,4R)-1-[3-oxo-3-(tetrahydro-pyran-4-yl)-thiopropionyl]-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid methyl ester (example 393d) was reacted with cyclobutylhydrazine hydrochloride (CAS Reg. No. 158001-21-9) to give the title compound as yellow oil. MS (ESI): m/z=542.4 [M+H]+.
