Reaction Steps
To the compound (352 mg, 0.931 mmol) obtained in Example 179a were added ethanol (4 mL), tetrahydrofuran (1 mL) and 2N aqueous sodium hydroxide solution (0.93 mL, 1.86 mmol), and the mixture was stirred overnight. The reaction mixture was extracted with water, and washed with ether. The aqueous layer was acidified with 6N hydrochloric acid, and extracted with ethyl acetate. The extract was washed with saturated brine, dried over sodium sulfate, and concentrated under reduced pressure. The residue was recrystallized from ethyl acetate-hexane to give the title compound (261 mg, 77%) as colorless crystals.
