Procedure
A solution of EXAMPLE 112A (64 mg) in dichloromethane (4 mL) was treated with trifluoroacetic acid (2 mL) at room temperature for 1 hour. The reaction mixture was concentrated and 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 339 (M+H)+; 1H NMR (300 MHz, CD3OD): δ 1.64-1.73 (m, 4H), 2.36-2.44 (m, 2H), 2.46-2.53 (m, 2H), 2.57-2.69 (m, 1H), 2.81-2.93 (m, 1H), 3.94-4.04 (m, 1H), 3.98 (s, 2H), 4.08-4.20 (m, 1H), 5.07 (dd, J=9.49, 7.80 Hz, 1H), 7.03 (d, J=8.14 Hz, 1H), 7.30 (t, J=7.80 Hz, 1H), 7.41 (t, —1.70 Hz, 1H), 7.49 (dd, J=7.97, 1.53 Hz, 1H).
