실험 절차
To a suspension of EXAMPLE 34B (2.15 g, 4.87 mmol) in 60 mL ethanol/water (5:1) was added powdered potassium hydroxide (1.09 g, 19.46 mmol). The suspension was heated at 50° C. for 3 hours, at which time the reaction was homogeneous. The solvent was removed and the crude material was dissolved in ethyl acetate, washed with water, and brine, dried over magnesium sulfate, filtered and concentrated. The crude material was purified by flash chromatography (Analogix 280, gradient elution, 20-100% ethyl acetate/hexane) to give the title compound. MS (ESI) m/e 301.9 (M+H)+.
