Procedure
A solution of EXAMPLE 258 (35 mg, 0.1 mmol) in trifluoroacetic acid (5 ml) was stirred at room temperature for 1 hour, and was concentrated. The residue was purified by HPLC (Zorbax® C-18 ODS packing material [Agilent Technologies, Santa Clara, Calif.], 0.1% trifluoroacetic acid/CH3CN/H2O) to provide the title compound as a trifluoroacetic acid salt. MS (DCI/NH3) m/z 249 (M+H)+.
