Procedure

A mixture of Example 609A (23 mg, 0.033 mmol) in 1:1 MeOH:dioxane (2 mL) was treated with tetraethylammonium fluoride hydrate (49.4 mg, 0.33 mmol) at 50° C. for 24 hours. The reaction was then cooled to room temperature, concentrated, diluted with ethyl acetate, washed with water and brine, dried (MgSO4), filtered and concentrated. The residue was purified by preparative HPLC to provide the title compound.
