Procedure

A solution of Example 164D (0.100 g, 0.1912 mmol) in dichloromethane (4 mL) was treated with trifluoroacetic acid (4 mL) at room temperature for 1 hour. After concentrating in. vacuo, the resulting oil was partitioned between ethyl acetate and aqueous NaHCO3, the organic layer was removed and the bicarb layer extracted 3× with ethyl acetate. The combined organic layers were dried over MgSO4, filtered, and concentrated in. vacuo to yield a solid that was used without further purification.
