実験手順

A solution of 3-[carbamoylmethyl-(4-chloro-benzyl)-amino]-pyrrolidine-1-carboxylic acid tert-butyl ester (0.49 g, 1.32 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: 267 (M+1), UV retention time: 0.82 min.
