Procedure

In analogy to the procedure described in example 253a, (2S,4R)-4-(4-fluoro-2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester 2-methyl ester (example 208 c) was treated with trifluoroacetic acid in dichloromethane to give the title compound as yellow oil. MS (ESI): m/z=356.1 [M+H]+.
