Participants

Reaction Steps

A mixture of Example 166A (779 mg, 2.00 mmol) and solid potassium hydroxide (841 mg. 15.0 mmol) in ethanol (10 mL) and water (2 mL) was heated to reflux for 1 hour. After cooling to room temperature, 1N HCl was added to adjust the pH to 1. The mixture was extracted with ethyl acetate (4×20 mL). The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated by rotary evaporator to afford a crude powder. The product was recrystallized from ethyl acetate/hexanes to afford the title compound. MS (ESI+) m/z 362.1 (M+H)+.
