Versuchsvorschrift

A solution containing the crude product from Example 9A in THF (150 mL) was treated with an HCl solution (5 mL, 4 N in dioxane), and the mixture was heated at 60° C. for 2 hours, cooled to 25° C. and concentrated. The concentrate was partitioned between ethyl acetate and saturated NaHCO3. The organic phase was washed with brine, dried over MgSO4, filtered and concentrated to give the title compound (0.36 g, 61% yield).
