Versuchsvorschrift

A suspension of the product of Example 91B (223 mg, 0.4404 mmol) and iron powder (98 mg, 1.762 mmol) in acetic acid (5 mL) and ethanol (5 mL) was heated at reflux under a nitrogen atmosphere for 30 minutes. The reaction was cooled to room temperature, diluted with water (50 mL), and treated with solid sodium carbonate until the pH was 6. Extracted with ethyl acetate (100 mL), washed the organic with brine (50 mL), dried over anhydrous sodium sulfate, filtered, and concentrated by rotary evaporation under vacuum. Co-evaporating the resulting oil with methylene chloride/hexanes gave the title compound as a light tan solid (195 mg, 93%).
