Versuchsvorschrift
To a solution of a corresponding 4-[(benzylamino)]-pyrrolidine-1,2-dicarboxylic acid 1-tert-butyl ester 2-methyl ester in DCM, cooled to 0 degree is added TrocCl and TEA. The mixture is stirred overnight, washed with Na2CO3, brine, dried and concentrated in vacuo to give 4-[(benzyl)-(2,2,2-trichloro-ethoxycarbonyl)-amino]-pyrrolidine-1,2-dicarboxylicacid 1-tert-butyl ester 2-methyl ester (19).
Aufarbeitung
- washwashed with Na2CO3, brine
