실험 절차
A solution of 3-[2-(4-benzyloxy-phenyl)-ethyl]-3-hydroxy-4-methyl-pentanoic acid from Example RRRR (10.1 g, 29.5 mmol), MeOH (300 mL), and H2 SO4 (0.2 mL) was refluxed for 3 days. The reaction was stripped to dryness and the product was partitioned between ethyl acetate and 5% NaHCO3. The solution was dried (MgSO4), and concentrated to give the title compound.
