실험 절차
To a solution of the product of EXAMPLE 30A (0.3 g, 0.96 mmol) in ethanol (2 mL) was added 2N aqueous sodium hydroxide (2 mL) and the mixture was stirred at room temperature for 12 hours. Ater concentration, the residue was diluted with water and extracted with ethyl acetate. The aqueous phase was acidified to pH 2-3 with concentrated HCl and extracted with ethyl acetate (3×5 mL). The combined organic phase was washed with brine, dried over anhydrous sodium sulfate, filtered and concentrated. The title compound was used in the next step without further purification.
