Procedure

A solution of 10.0 mg of the product of Example 4 was dissolved in 0.5 ml of pyridine and treated with 2.6 μL of acetic anhydride. The solution was stirred overnight and diluted with 5 ml water and was extracted with ethyl acetate (2×5 ml). The combined organic phase was dried over MgSO4, filtered and concentrated in vacuo to give the title compound.
