실험 절차

A mixture of compound 26c (420 mg, 1.03 mmol) and LiOH (100 mg, 4.0 mmol) in a solvent mixture of THF/MeOH/H2O (2/2/2 mL) was stirred at room temperature for 4 h, at which time it was brought to pH 5 by the addition of 2N HCl (aq). The mixture was extracted with EtOAc (3×). The combined extracts were dried over Na2SO4, filtered, and concentrated under reduced pressure. The resultant residue (crude compound 26d) was dried under reduced pressure for 18 h, and used in the following step without further purification.
