Trifluoroacetic acid → 2-[(4-chloro-benzyl)-pyrrolidin-3-yl-amino]-N-ethyl-acetamide

Participants

Reaction Steps

A solution of 3-[(4-chloro-benzyl)-ethylcarbamoylmethyl-amino]-pyrrolidine-1-carboxylic acid tert-butyl ester (0.12 g, 0.31 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 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: 296 (M+1), UV retention time: 1.02 min.
