실험 절차

To a solution of compound 147-B (0.508 g, 2.63 mmol) in a mixture of MeOH (15 mL) and H2O (3 mL) was added 3N NaOH (1.9 mL, 5.66 mmol) and the reaction mixture was stirred at ambient temperature for 5 h. The solvent was evaporated under reduced pressure, the residue dissolved in H2O, and acidified with 1N HCl. The precipitate was filtered, washed with H2O, and dried under vacuum to afford compound 147-C as a white solid (0.366 g, 78%). MS: m/z 180.0 (MH+).
