Procedure

To a solution of EXAMPLE 55A (480 mg, 1.76 mmol) in methylene chloride (10 mL) was added trifluoroacetic acid (5 mL). The solution 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 353 (M+H)+; 1H NMR (500 MHz, CD3OD): δ 1.68-1.74 (m, 4H), 2.43-2.48 (m, 2H), 2.48-2.54 (m, 2H), 3.19-3.29 (m, 3H), 3.67-3.97 (m, 5H), 4.04 (s, 2H), 7.30-7.33 (m, 1H), 7.33-7.36 (m, 1H), 7.36-7.39 (m, 1H), 7.44 (t, J=7.48 Hz, 1H).
