실험 절차
To a solution of compound 1 (1.26 g, 10 mmol) in methanol (30 mL) was added sulfuric acid (0.5 mL). The resulting mixture was refluxed for 2 h and the solvent was evaporated. The residue was dissolved in EA (60 mL) and washed with brine, dried over Na2SO4. Then filtered and concentrated to give the product.
