실험 절차

To a solution of Example 57a (0.250 g, 0.50 mmoles) in DMF (5 ml), ethanol (2.5 ml) and water (2.5 ml), 3-hydroxymethylphenylboronic acid (0.115 g, 0.757 mmoles) and sodium carbonate (0.267 g, 2.53 mmoles) were added and the system is degassed for 30 min. Tetrakis triphenylphosphine Palladium (0.115 g, 0.099 mmoles) was added under nitrogen atmosphere and heated to 80° C. After 12 h, the reaction mixture was celite filtered, concentrated and extracted with ethyl acetate. The organic layer was dried over sodium sulphate and concentrated under reduced pressure. The crude product was purified by column chromatography with methanol: dichloromethane to afford the title compound as brown solid (0.116 g, 44% yield). MP: 219-223° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 8.23(s,1H), 8.05(dd, J=8.0, 1.6 Hz, 1H), 7.77(m,1H), 7.58(s,1H), 7.50(m, 3H), 7.44(d, J=8.5 Hz, 1H), 7.41-7.31(m, 6H), 5.52(s,2H),5.27(t, J=5.8 Hz, 1H), 4.57(d, J=5.7 Hz, 2H). Mass: 476.31(M++1).
