Reaction Steps

To a solution of Example 32C (372.1 mg, 0.69 mmol) in methanol (5 mL) was slowly added a solution of 4 M HCl in dioxane (1.6 mL, 6.4 mmol) at 0° C. over 10 minutes via addition funnel. The mixture was allowed to stir for 5 hours at room temperature and then was concentrated under reduced pressure to provide the titled compound.
