Procedure

A mixture of Example 69B (7.50 g, 22.0 mmol) and 2,2,2-trifluoroacetic acid (13.5 mL, 176 mmol) was stirred at 22° C. for 8 hours. The volatiles were removed under reduced pressure and the residue was diluted with dichloromethane and washed with saturated aqueous NaHCO3. The organic extract was dried over Na2SO4 and concentrated to give the title compound. MS (ESI+) m/z 242 (M+H)+.
