実験手順

1,1-Dimethylethyl N-((7-(3-pyridyl)-4-hydroxy-1,1-dimethyl-2-oxo-naphthalen-3-yl)carbonyl)glycinate (184 mg, 436 μmol) was stirred in TFA (2 mL, 26924 μmol) at room temperature for 30 minutes. The reaction mixture was partitioned between water and EtOAc. The organic layer was separated, and the aqueous layer was extracted with EtOAc (2×). The combined organic layers were dried (MgSO4) and concentrated in vacuo to give the desired product as a yellow solid (95 mg). MS (m/e)=367.2 (M+H)+. Calculated for C21H19NO5 366.12.
