Reaction Steps

A mixture of 1.0 eq of 95 and 2.3 eq of potassium acetate in 70 mL of EtOH and 140 mL of H2O was refluxed for 17 hrs. After cooling to rt and rotary evaporation of the EtOH, the solution was made alkaline with 10 N NaOH. The mixture was extracted with chloroform (3×50 mL). The combined organic extracts were dried over MgSO4 and vacuum filtered. The filtrate was rotary evaporated and dried under vacuum to yield 96.
