Procedure

The product of Example 18A (160 mg, 0.57 mmol) was coupled with 3-aminophenylboronic acid (Lancaster, 157 mg, 1.14 mmol) according to the procedure of Example 1B. The title product was purified by chromatography (SiO2, CH2Cl2:MeOH:NH3—H2O, 90:10:1, Rf. 0.1) as solid (144 mg, yield, 86%). 1H NMR (300 MHz, MeOH-d4) δ 1.48-1.62 (m, 1H), 1.65-1.90 (m, 2H), 2.01-2.15 (m, 1H), 2.21-2.29 (m, 1H), 2.74-3.04 (m, 5H), 3.36-3.47 (m, 1H), 5.12-5.20 (m, 1H), 6.75 (ddd, J=8.2, 2.1, 1.0 Hz, 1H), 6.89 (ddd, J=7.4, 1.7, 1.0 Hz, 1H), 6.93 (t, J=1.8 Hz, 1H), 7.20 (t, J=7.8 Hz, 1H), 8.74 (s, 2H) ppm. MS (DCl/NH3) m/z 297 (M+H)+.
