실험 절차

The product from Step C was dissolved in methanol and 5% aqueous sodium hydroxide added. After 1 h, methanol was removed in vacuo, and the residue partitioned between ethyl acetate and 10% aqueous HCl. The organic layer was washed with saturated brine, and dried over MgSO4. Filtration and concentration provided the title compound.
