Procedure
A stirred solution of the product of Example 203 (11.48 g, 24.24 mmol) in ethyl acetate (150 mL) was treated by slow addition with of a 1M HCl/ethyl acetate (24 mL, 24 mmol) solution at ambient temperature. An additional EtOAc (50 mL) was added to the resulting white precipitate, and the slurry was stirred approximately 1 hour at ambient temperature. The product slurry was pressure filtered through a stainless steel filter under nitrogen. The collected product was kept under a steady nitrogen purge for approx. 2 hrs. The filter was then placed in a vacuum oven overnight at 60° C. The product was dried to constant weight in a drying oven at 75° C. to afford 10.38 g (84.1%) as a white solid.
