Reaction Steps

In analogy to the procedure described in example 308d, a mixture of (2S,4R)-1-(3-oxo-thiobutyryl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid methyl ester (example 192 g) and of (2R,4R)-1-(3-oxo-thiobutyryl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid methyl ester was reacted with N-(3-hydrazino-phenyl)-acetamide hydrochloride (CAS Reg. No. 1187369-44-3) to give a mixture of the title compound and (2R,4R)-1-[2-(3-acetylamino-phenyl)-5-methyl-2H-pyrazol-3-yl]-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid methyl ester as yellow solid. MS (ESI): m/z=551.2 [M+H]+.
