실험 절차

A mixture of compound 30c (320 mg, 1.15 mmol), LiOH (110 mg, 4.59 mmol) in THF/MeOH/H2O (3/3/3 mL) was stirred for 4 h. A 15% aqueous citric acid solution (10 mL) was added. The mixture was then extracted with EtOAc (3×). The combined organic extracts were washed with brine, filtered, dried over Na2SO4, and concentrated under reduced pressure. The resultant residue (compound 30d, 290 mg) was dried under reduced pressure for 18 h and was used without further purification.
