HCID 667711861-(2-tert-Butyl-phenyl)-4-(2-trifluoromethyl-benzenesulfonyl)-pyrrolidine-2-carboxylic Acid Ethyl Ester

Procedure

In analogy to the procedure described in example 343d, (2-tert-butyl-phenylamino)-acetic acid ethyl ester (CAS Reg. No. 959563-17-8) was reacted with paraformaldehyde and 1-ethenesulfonyl-2-trifluoromethyl-benzene (example 243c) to give the title compound as colorless oil. MS (ESI): m/z=484.4 [M+H]+.
