実験手順

To a solution of tert-butyl 3-(1-(4-(2,3-dimethylphenoxy)butanoyl)-1,2,3,4-tetrahydroquinolin-5-yl)benzylcarbamate (0.12 g, 0.227 mmol) in DCM (2.5 mL) at 0° C. was added TFA (0.35 mL, 4.54 mmol) dropwise. The reaction mixture was slowly warmed to room temperature and stirred for 16 h. After this time, the reaction mixture was quenched with 50% saturated NaHCO3, and the aqueous phase was extracted with DCM. The combined organic layer was dried over anhydrous MgSO4, filtered, and concentrated in vacuo to afford the title compound (0.075 g, 77% yield). LCMS, [M+H]+=429.2.
