Trifluoroacetic acid → N-[(1S,2S,5R)-7-methyl-3-aza-bicyclo[3.3.0]oct-2-ylmethyl]-2,2,2-trifluoro-acetamide

Participants

Reaction Steps

To a cold (0° C.) solution of (1S,2S,5R)-2-[(2,2,2-trifluoro-acetylamino)-methyl]-7-methyl-3-aza-bicyclo[3.3.0]-octane-3-carboxylic acid tert.-butyl ester (1.51 g) in DCM (13 mL) was slowly added TFA (3.31 mL, 10 eq). The reaction mixture was allowed to warm at RT and stirred overnight. Solvent and excess of TFA were removed in vacuo and the product was used for the next step without further purification.
