실험 절차

A solution of 3-[(4-chloro-benzyl)-(2-hydroxy-ethyl)-amino]-pyrrolidine-1-carboxylic acid tert-butyl ester (0.22 g, 0.6 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: 255 (M+1), UV retention time: 0.34 min.
