The product of Example 8A (405 mg, 1 mmol) was treated with aniline (110 mg, 1.2 mmol) according to the procedure in Example 8B. The title compound was purified by chromatography (SiO2, CH2Cl2:MeOH:NH3.H2O, 90:10:1, Rf. 0.25) as solid (200 mg, yield, 54%). 1H NMR (MeOH-d4, 300 MHz) δ 1.42-1.56 (m, 1H), 1.62-1.88 (m, 2H), 1.99-2.12 (m, 1H), 2.14-2.22 (m, 1H), 2.73-3.02 (m, 5H), 3.27-3.38 (m, 1H), 4.51-4.59 (m, 1H), 6.80-6.87 (m, 1H), 6.94 (d, J=8.8 Hz, 2H), 7.06-7.15 (m, 4H), 7.18-7.26 (m, 2H), 7.44 (d, J=8.5 Hz, 2H), 7.49 (d, J=8.8 Hz, 2H) ppm. MS (DCl/NH3) m/z 371 (M+H)+.
