実験手順

A solution of (3R)-tert-butyl 3-(1-(4-(trifluoromethyl)phenyl)-1,2,3,4-tetrahydro-isoquinoline-2-carboxamido)piperidine-1-carboxylate (44 mg, 87 μmol, example 20) in TFA (30% in DCM, 2 mL) was stirred at RT for 30 min. The solvents were removed and EtOAc (5 mL) and saturated NaHCO3 (3 mL) were added to the residue. The solution mixture was then stirred at RT for 10 min. The organic layer was collected and the aqueous layer was extracted with EtOAc (2×2 mL). The combined organic extracts were dried over MgSO4, concentrated, and dried under vacuum to give the title compound as an off-white solid. MS (ESI, positive ion) m/z: 404 (M+H).
