(2S,4S)-1-[[N-[4-(2-tetrahydropyranyl)oxycarbonylbicyclo[2,2,2]oct-1-yl]amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile → (2S,4S)-1-[[N-(4-carboxybicyclo[2,2,2]oct-1-yl)amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile

Participants

Reaction Steps

(2S,4S)-1-[[N-[4-(2-Tetrahydropyranyl)oxycarbonylbicyclo[2,2,2]oct-1-yl]amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile (71.6 mg) was dissolved in acetic acid (4 mL) and the solution was stirred at room temperature for 6 hours. Subsequently, the reaction mixture was concentrated under reduced pressure and the residue was suspended in dichloromethane and was collected by filtration. This gave (2S,4S)-1-[[N-(4-carboxybicyclo[2,2,2]oct-1-yl)amino]acetyl]-4-fluoropyrrolidine-2-carbonitrile (31.4 mg).
