Versuchsvorschrift
A solution of 3-[(4-chloro-benzyl)-isopropyl-amino]-pyrrolidine-1-carboxylic acid tert-butyl ester in dichloromethane cooled at 0° C. was treated with trifluoroacetic acid (20%) and warmed to room temperature and stirred for 2 hours. The reaction mixture was concentrated in vacuo, diluted with ethyl acetate and free based with 10% aqueous sodium bicarbonate. The combined organics were dried over sodium sulfate. The product was used without any further purification. ESI-MS m/z: 253 (M+1, UV retention time: 0.59 min.
