The product of Example 18B (340 mg, 0.86 mmol) in CH2Cl2 (6 mL) was treated with trifluroacetic acid (Aldrich, 2 mL) at ambient temperature for 30 minutes and concentrated under reduced pressure. The title product was purified by chromatography (SiO2, CH2Cl2:MeOH:NH3.H2O, 90:10:1, Rf. 0.07) as solid (150 mg, yield, 58%). 1H NMR (300 MHz, MeOH-d4) δ 1.88-2.22 (m, 3H), 2.31-2.45 (m, 1H), 2.56-2.64 (m, 1H), 3.27-3.51 (m, 5H), 3.84-3.96 (m, 1H), 5.36-5.45 (m, 1H), 6.87 (d, J=8.5 Hz, 2H), 7.42 (d, J=8.5 Hz, 2H), 8.77 (s, 2H) ppm. MS (DCl/NH3) m/z 297 (M+H)+.
