Procedure

To a solution of Example 57b (0.350 g, 0.684 mmoles) in DMF (3.5 ml), ethanol (1.7 ml) and water (1.7 ml), 3-methyl-6-indazoleboronic acid pinacol ester 97 (0.353 g, 1.369 mmoles) and sodium carbonate (0.217 g, 2.05 mmoles) were added and the system is degassed for 30 min. Tetrakistriphenylphosphine Palladium (0.040 g, 0.034 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 (0.073 g, 21% yield). MP: 249-252° C. 1H-NMR (δ ppm, DMSO-d6, 400 MHz): δ 12.75(s,1H), 8.09(s,1H), 8.05(dd, J=8.0,1.6 Hz, 1H), 7.85(d, J=8.2 Hz, 1H),7.81(m,1H), 7.64(s,1H), 7.62(d, J=8.4 Hz, 1H), 7.51(t, J=7.3 Hz, 1H), 7.36(dd, J=9.3,1.0 Hz, 1H), 7.29(m,3H), 7.15(br s, 2H), 6.01(q, J=7.0 Hz, 1H),2.52(s,3H), 1.92(d, J=7.0 Hz, 3H). Mass: 514.18(M++1).
