To a solution of the carbamate above in DCM was added TFA (1:1 v/v). The reaction was stirred at rt for 30 min before being concentrated in vacuo. The crude residue was taken up in EtOAc, and washed with satd. aq. NaHCO3, brine, dried (MgSO4), and concentrated to afford (octahydrocyclopenta[c]pyrrol-1-yl)methanol as a pale yellow oil. To a solution of (octahydrocyclopenta[c]pyrrol-1-yl)methanol (1 equiv.) from the previous step in DMF was added DIPEA (2 equiv.) followed by 5-methyl-2-(2H-1,2,3-triazol-2-yl)benzoic acid (1.5 equiv.) and HATU (2 equiv.). The reaction was allowed to stir at rt for 15 h, and was then concentrated in vacuo to remove the DMF. The crude residue was taken up in EtOAc and washed with 1 M HCl, sat aq. NaHCO3, brine, dried (MgSO4), and concentrated. The crude residue was purified by chromatography on silica gel (EtOAc/hexanes) to give the title compound as a clear oil. MS (ESI) 326 (M+H).
