Procedure

A 2N aqueous sodium hydroxide solution (0.6 mL) was added to an ethanol solution (0.3 mL) of Compound 22 (194 mg) and the mixture was stirred at room temperature for 1 hour. 2N hydrochloric acid was then added to the reaction mixture while cooled with ice, and the mixture was neutralized. The product was extracted with chloroform (5 times). The organic layer was dried over sodium sulfate, filtered, and concentrated under reduced pressure to give 38 mg (23% yield) of the desired product.
