A solution of 3-[(4-chloro-benzyl)-(2-methoxycarbonyl-ethyl)-amino]-pyrrolidine-1-carboxylic acid tert-butyl ester (0.08 g, 0.2 mmol) in dichloromethane cooled at 0° C. was treated with trifluoroacetic acid (20%). The resulting mixture was warmed to room temperature and stirred for 2 h. 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: 297 (M+1), UV retention time: 1.05 min.
