実験手順
In analogy to the procedure described in example 192 h, (2S,4R)-1-(3-oxo-thiobutyryl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid methyl ester (example 192 g) was reacted with 2,2,2-trifluoroethylhydrazine (CAS Reg. No. 5042-30-8) to give the title compound as yellow solid. MS (ESI): m/z=500.2 [M+H]+.
