실험 절차

To a solution of the ester from step (a) above (2.98 g, 10 mmol) in MeOH (5 mL) was added saturated solution of hydrogen chloride in EtOAc (50 mL) and the mixture was stirred at room temperature for 4 h. The solvent was removed in vacuo, and the residue was washed with EtOAc and dried in the air to provide the title compound as a light-yellow solid. MS (ESI, pos. ion) m/z: 198 (M+1).
