Procedure

A solution containing the product from Example 15B (2.3 g, 6.37 mmol) in dichloromethane (15 mL) was treated with trifluoracetic acid (15 mL), stirred at 25° C. for 5.5 hours and concentrated to give the title compound (3.42 g) as the trifluoroacetic acid salt, which was used without further purification.
