HCID 86646850(2S,4R)-1-(3-Cyclopropyl-3-oxo-propionyl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic Acid Methyl Ester

Procedure

In analogy to the procedure described in example 192f, (2S,4R)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic acid methyl ester (example 192e) was reacted with 3-cyclopropyl-3-oxo-propionic acid tert-butyl ester (CAS Reg. No. 134302-07-1) to give the title compound as brown oil. MS (ESI): m/z=448.1 [M+H]+.
