실험 절차

Methyl ester 1 (8.45 g, 18.8 mmol) was dissolved in THF (35 mL) and sodium hydroxide (1.13 g, 28.2 mmol) pre-dissolved in water (10 mL) was added. A further 15 mL of THF and 20 mL of methanol were added to obtain a homogenous solution. The reaction mixture was stirred at rt for 18 h before being concentrated in vacuo. The residue was partitioned between EtOAc and 1M hydrochloric acid. The aqueous phase was extracted twice more with EtOAc and the combined organic extracts were washed with brine, dried (MgSO4), filtered and concentrated in vacuo to yield a white foam, 7.25 g, 89%.
